ABSTRACT:
A lock, which releasably affixes to the end of a cylindrical rod, includes a torus-like case having a central cylindrical passageway that fits over the rod. A spring normally urges a pair of cylindrical pistons located in the case to a locked position where they partially extend into the passageway by a spring. An actuation mechanism allows the pistons to be moved to an unlocked position where they are completely contained within the case by pressing a plunger that extends through the case. The rod contains a plurality of pairs of openings at specified locations along the rod that receive the pistons when the lock is placed on the rod.
