ThinPlug/ThinCharger replacement safety pin

I'm happy user of ThinPlug cable (recently Lindy ThinPlug) for years, but unfortunately one of my two cables had folding pin broken. So I decided to create one from scratch :-)

After two attempts, created one which fits perfectly and works.
Should also fits thincharger - if required.

(ThinPlug was one of first and probably only one cable approved to use with British standard sockets which folds flat. Not sure why it was cancelled)
