Does anyone I Remember those weird connectors on vacuum cleaners with two
pins and if you were lucky and earthed strap on the sides that connected to
springs on the inside of the socket which had the pins. These were always
working loose and getting hot and sparking ...

Yes, rather atupid place for a conector. Captive mains leads
today are much better.

However, the basic connector you described, although
physically very different, worked in the same way as the
Schuko connector used in most European countries.
