I am trying to buy a single socket for one of those standard 2-pin
European (French) plugs which are commonly used on table lamps and

plugs but are slimmer and have 'triangular' ends. I think they're
rated at 2.5 amps.

It is probably easier to buy a "two pin plug" to fused 13A plug adapter.

I know the plug will fit in a bigger round socket or in a German
Schuko socket but I'd prefer to find one specifically for the smaller
plugs so that a big round one won't fit.

I want one that will flush mount if possible, I don't have much
clearance available where it's going to be installed.

Shaver socket is the only legitimate UK mains connector with that two
pin profile.
