There is spring loaded metal slug behind the knuckle. The spring breaks so the slug does not engage the knuckle to keep it closed. You have remove the knuckle to fix it. I replace both springs at that point.

Is the knuckle spring broken? If so, the repair is the same as with a magnetic coupler, where you remove the rivet, take out knuckle (tc21), remove old spring (tc22)/replace with new spring, and put back together with rivet (tc23). If that isn't broken, you will have to disassemble, as if replacing (tc22 spring), to get to the internal plunger and spring (plunger tc-113, plunger spring tc-112). Replace the broken part, and reassemble, and all should be good.
