Switching out old broken shaver socket for new one. Having trouble working out how to unwire the existing socket
For over a year, this &quot;unanswered&quot; question has had an answer and acceptance in the comments:

Looks like push-to-release connectors. So try pushing and removing the
wire at same time.... at worst you can cut the wires as next as you
can to the box and rewire the new outlet. – DDS May 19 '18 at 9:22
Turns out they were push to release connectors. Thanks for the
assistance guys. – Iain May 19 '18 at 13:08
