device for loesbaren formschluessigen coupling components

摘要

A separable coupling includes a female coupling member having a first circular peripheral wall provided with circumferentially spaced coplanar first slots and cam faces leading radially inwardly from the outer edge of the peripheral wall towards respective slots. A male coupling member has a second circular wall which slideably telescopes the first peripheral wall and has slots registering with the first slots. A locking member formed of resilient wire is located in the male coupling member and has integrally formed outwardly directed ears with outwardly converging side edges engaging corresponding pairs of registering slots. The peripheral walls may be conical or cylindrical and may be continuous or interrupted along their lengths. In joining the coupling members they are axially brought together with the cam faces contracting the ears until they register with and expand in the slots and by twisting one of the members relative to the other the ears are contracted out of the female slot permitting uncoupling.
