If you can find one, a clock point is excellent for this.
They are designed to be connected to a lighting circuit,
can be unplugged for maintenance, and they take a fuse.

Are these the same as BS546 round pin sockets?

No, and there's no standard style for them (they aren't
interchangeable between different manufacturers, and
they're sold as a plug and socket matched pair).
Some take the small cartridge fuse used in some shaver
adaptors, and some take a regular BS1362 plugtop fuse.
They were normally available in surface mount or BESA
box mounting types. There's usually a screw or knurled
nut to stop the plug dropping out (not that it's likely
to -- this was probably to act as a bit of a "safety
chain" if the clock fell off the wall).

A fused 2A BS546 round pin plug/socket would be pretty
equivalent.
