At first glance I thought they may be for 12 V DC, however I would have expected one pin to be larger than the other for polarity reasons, with 2 of them I wonder if they could be for stereo speakers?

Yes, because showing the comparison of a USB plug proves that my theory is now ruled out.
I have even searched on Google 'images' for numerous pictures of various sockets and can't find anything at all that resembles it.
The only other theory I can think of is, as the Freedom caravan is Polish whether it's a foreign type of 12 volt socket that's not familiar in the UK?

Could well be. What doesn't make sense to me is why is says "10A 24V" on the flap. Why 24V when 'vans have 12V circuits - just because it's a convenient socket to run 12V through even though the label is wrong?

Would this plug fit?
Ooh, looks close to the right size. I'll have to measure tomorrow and report back. Would the pins be the same size, or one pin larger than the other for polarity reasons as Pickled Onion mentioned?
Thanks for helping me out with this

Thanks for the suggestions.
If it makes any difference, the location is on the side of the 'fridge housing, under the seat/bed.
The ports are too narrow and only half the height, of a USB plug.
It is on a 2008 Polish Freedom van.
I've tried to take more pictures - one showing the USB plug for scale, and the other showing the writing on the socket cover flap - 10A 24V.
Does any of this help point to their purpose?
That writing suggests 10Amps 24Volts. I don't think I have ever seen a caravan with a 24 Volt supply, but then I haven't seen many foreign caravans. Have you tried to see if the socket is live?
The 10A 24V indicates it is a low voltage socket. it says 24volt because that is what it is rated to not what it is necessarily connected to in the van. it's a standard outlet suitable for 12 or 24volt.
It's the sort of outlet you'd expect for a TV Is it inside the seat box or just in the front face so you an access it from inside the caravan.
We had some sockets which took the plug Hacksaw showed. But they didn't look like these sockets.
This is a better view of what seems to be a very similar plug, with apparently identical pins but with L and N marked on the case, so presumably intended for use with polarity-sensitive items, though it's not obvious which way round you'd use them in your sockets.
Might be an idea to put a meter across your sockets to check voltage and polarity?

I have these 12 volt plugs in my caravan and you will find that one blade is narrower than the other so they cannot be plugged in incorrectly whereas the socket the OP has indicated the slots are identical.

I agree with Tango55 on this one, howeve the 24v intrigues me, trucks use 24v DC, I wonder if it ever used a power supply from a truck at some time in it's life? Trucks often have 24v TVs for use in them, you still have the polarity problem unless the cover makes it impossible to reverse the plug.

Why don't you simply put a multi-meter over the terminals to check voltage and polarity. If it's pumping out 12v, buy a conventional 12v socket and replace it.
I would suspect that this type of socket had it's own plug that you could only connect one way round (maybe restricted by the lid), but just test it instead of speculation.
That's my 24 volt guess out of the window then. As we've suggested it's a 12 volt socket but I doubt that you will ever get the matching plug that went with it. If you need one, just swap it for a conventional type, if not, ignore or remove them.
