ABSTRACT:
A fast action disconnect for releasably coupling parts together such as a power line stringing block and a conventional dog nut at the lower end of a power line insulator. The disconnect has a receiving socket for the dog nut insertable through one side of the disconnect and includes a barrier for releasably but positively locking the dog nut assembled to the disconnect. The barrier is movable between a retracted locking position and an extended release position permitting disassembly of a dog nut relative to the main body of the disconnect.
