I'm hoping someone can help me identify (and thus hopefully find a
replacement for) a plug used inside an aged hi fi loudspeaker.

Yes, no name I ever remember.

I'd like to replace it with a new plug. But I can't even look for
one, because I don't know what this type of plug/socket is called

You may be able to solder wires to a couple of split pins of the right size
to make a connection.

Heat shrink could ID and insulate them.
