Remember the old UK bakelite 13A plugs?
If you dropped them on a stone or concrete floor they would crack and/or break.
If the plug was deemed to be repairable it was a case of dismantle the plug and grab the tubes of Araldite from where they were stored.
Then carefully glue the broken bits back together, taping them for 24 hours while the epoxy resin hardened and then the plug could be screwed back together the day after.
