On my push bike I have a dynamo, which powers front and rear lights.
The rear light has a pair of spade connectors which can be used to wire in
an extra light (if so desired).

What I am looking for is a weather resistant plug and socket which can be
used to plug in an optional additional light.

A bonus would be if it came apart easily instead of breaking if the lead
was tugged.

More detail; I was considering having the extra light on a rear pannier
and being able to take the pannier off and disconnect the light, fit the
pannier and connect the light, and when I forgot to disconnect the light
when taking the pannier off the plug and socket would come apart without
damage (this assumes the half on the bike is firmly fixed, of course).

I thought that this kind of arrangement was called a snatch plug but
searching so far hasn't shown me what I was looking for.

Take a look at Torberry connectors:-

Seconded. You can get rubber boots for them but with a bit of WD40 on
now and again (the right use for WD40 g) they survive pretty well
exposed to the elements.

I use them on things like portable solar panels (apart from RC cars
etc) and they do pull apart if snatched.

If you don't want them to you can put a small cable-tie round them.

Not 'small' as cycle gear goes but if tucked up under some panniers
....
