ABSTRACT:
A safety cage including two end plates connected by straps extending therebetween is adapted to be placed over an assembled quick connect-disconnect coupling, and the end plates engage behind abutment surfaces on the coupling to prevent accidental separation of the coupling elements. The cage also carries a pair of spaced vertical bars that engage a shoulder on the operating sleeve of the coupling, and lock it against any axial movement. The coupling includes an abutment ring that prevents any forward shifting of the sleeve because of component wear, further eliminating the possibility of accidental separation.
