ABSTRACT:
A lock having a first portion for engaging a first coupling and in concert with a shoulder of a second portion to lie in the plane of the lip of a second coupling inhibits uncoupling rotation. A third portion of the lock for engaging the first coupling maintains the shoulder in the plane and the lock is further maintained in position by a fourth portion engaging both couplings. The first and third portions are in substantially the same plane for ease of insertion of the lock.
