Ah! Keynectors. Thats the name I remember.

They were deemed 'less safe' that the Safebloc as they only had a
single phase disconnect and I suspect that was the main reason they
died a death in the catalogues a decade or so ago.

It's not a huge problem if it's a permanent installation on a test
bench but move it into the field and a phase/neutral reversal could
leave a piece of equipment live - if you were stupid enough to go
inside said equipment relying on the keynector for isolation.
