How do I fit these two hoses together?

No idea.

But, go to the wall, and show us where that hose comes from. Then go behind the wall, and see where the supply pipe is. Find the valve, and turn it off.

If there really isn't a valve, then do everything you can to ID who installed that pipe, and I will personally help you to k$^&£&*% ^&*^&$£"! %^&^ out of him.

Oh, and could you provide the make and model of both the old and new !!!!!!, please?

Sorry, was silly of me not to include pictures of the mains source at the wall and beyond. I've added pictures 06 and 07 to do that. I can't follow the path fully, as I'd need to remove all of my kitchen cabinets. I suspect it goes to under the main kitchen sink, but we've tried every single tap there and none of them turn this feed off (expect obviously the main tap which turns off all water everywhere).

To explain, I bought this house from a builder about 10 years ago who had built it for his family to live in, which they did for the 7 years before me. That being the case, it seems he cut all sorts of corners!

Old and new fridges do you mean?
Old: Maytag GC2225GEKB
New: Samsung Series 8 RS68A884CB1/EU

To be honest, whilst it is annoying not having a tap to turn off the water to the fridge, I've never needed to do so in the 10 years I've lived here, so if I can get the whole thing connected then I can live with the lack of a tap...

Ah, thanks. So, does pic 7 show the same pipe that was supplying the old fridge? If so, what diameter is it - 10mm? If so, you just need standard 10mm plumbing pushfits.
In which case, with the mains off, you can cut that pipe, shove a support insert into each pipe end, and slot them into an isolating valve.
And then turn your mains back on, and start to live again.

Then contact Samsung, or read this instructions, on what's needed to connect :-)

Pic 7 shows what I believe to be the pipe that ultimately ends up as the water feed (I can't be 100% certain as it's in the wall, but given its position, I assume that the pipe in pic 7 goes into the wall then comes out as the pipe in pic 6.

Silly question, but how can I tell the diameter if I can't get to the inside of the pipe? That metal fixing on the end won't come off by hand - perhaps I need to cut it off? (I note that's what you suggest in your next sentence anyway). But looking at it, 10mm sounds right. However the white pipe is definitely nowhere near 10mm, I measured the inside as best I could and it seems to be about 4-5mm, god knows what size pipe that is (EDIT: OUTSIDE diameter is about 6mm, so I reckon it's a 1/4 inch - I didn't realise it was measured from outside...). I should be standard though as that white pipe is the Samsung kit. Anyway, it's nowhere near 10mm, so how would that work with a 10mm 'plumbing pushfit'?

(Sorry if my questions sound dumb, I'm definitely not a plumber, I just thought this was going to be really easy ).

Didn't it come with the pipes detailed in the manual (page 34)?

Yes but those pipes only cover doing it from a normal tap.

The fridge pipe is probably 1/4 inch - so you need a 1/2inch to 1/4 inch push-fit reducer (probably).  Maybe 3/8 to 1/4.

I think you're right. So, would this do the job?

02: The inlet connection coming from the wall. The main hose body is much fatter than the fridge hose, so it won't fit the filter.

03: Water filter connection.

04: Fridge connection hose - this is the size I need the water mains hose to be in order to fit into the filter.

05: How do I safely and securely connect these two together?

06: Mains hose going into the wall.

07: Path of mains hose going under kitchen units.

Ok, I'd wrongly assumed some things...

The plumbing shown in Pic 7 looks like 'normal domestic plumbing' using 'plastic push-fits'. If so, the pipe will be fairly rigid, which means that this pipe is not the same pipe in Pic 6 that you see coming through the wall - in fact that Pic 6 'pipe' is not pipe but 'hose'. It's flexible, and has a purpose-made fitting on the end which presumably fitted the Maytag. I suspect it was supplied with the Maytag, and that fitting is likely to be 1/4" (6.35mm) as shown on page 10:

https://www.maytag.com/content/dam/global/documents/201012/owners-manual-W10299703-RevB.pdf

In which case, it is only designed for that model, so whilst you may be able to connect to it, you'd likely be better off getting rid, and going back to where this hose is teed from the normal domestic plumbing.

There will be a point where this occurs, and almost certainly you will find it if you look properly! And it will most likely have a 'tap' on it to shut the water off. Where does that wall go - what's behind it? Have you looked inside every kitchen base unit to see if there's a mysterious fitting in there? Under the sink unit? Are you sure?!

That brings us to the Samsung.

This shows the connection on the fridge itself? (Ah, it's the separate filter?)

And that white pipe also came with it?

That looks like 'rigid' pipe, so will be similar in material to the domestic plumbing seen earlier - but smaller diameter.

So, how does that pipe connect with that fitting above? Does it just push into that grey collar and 'catch'? (Ah, yes, it almost certainly does.)

What outside diameter is that pipe?

Pages 36-ish onwards suggest that the supplied pipe is rigid, thick-walled, and does not need support sleeves inside them Ie, no mention of 'sleeves'. (See the 'domestic' plastic pipe in pic 7? That must have support sleeves fitted, fyi.)

To fit it to the filter cartridge, you cut the pipe end straight and cleanly, make sure it has no burrs, and you push it into that grey end fitting of the filter. It will be grabbed and held in there. To release, you push that grey collar inwards into the filter, and then you can pull out the pipe. To prevent this happening accidentally, there is a grey U-clip which goes behind that collar to prevent it from being pushed in. 
That's my best interpretation of the pretty weak instructions.

Can you find all these bits? Cool.

The kit should also have a fitting which looks a bit like a washing machine connector, and the other 'house' end of the hose goes there - you then connect that to your supply tap (when you find it), as I suspect the most common fitting on that tap will be a washing-machine type.

Really, to try and connect this new Samsung's rigid hose to the Maytag's old flexi hose is not ideal, tho' it can be done - you will need a suitable connector for that hose end fitting. The sensible thing, I think, is to trace that old hose, and find out where it's going. Then start anew.

Right, an update:

We went to a couple of plumbers' merchant's, neither could help us, both said it's a weird size pipe etc. THen we went to a heating specialist, who was incredibly helpful, tried 5 or 6 different things from his storeroom, and eventually sold us the white plastic part below. He did say he can't guarantee it will work and won't leak, but it's been 6 hours so far, and no problems (touch wood).

If anyone thinks I should have concerns about the new part in my set-up, please let me know.

Thanks to everyone who helped / tried to help (particularly ThisIsWeird who has gone to great lengths - many thanks).
