ABSTRACT:
A brake hose coupling for coupling to a glad hand body. The glad hand body has a primary port and a pair of primary flanges bordering and angularly spaced about the primary port. The brake hose coupling has a coupling body with a complementary port and a pair of complementary flanges adapted to rotate coaxially into engagement with the primary flanges of the glad hand body The complementary flanges border and are angularly spaced about the complementary port. The brake hose coupling also has a lock with a latching member mounted to reciprocate on the coupling body adjacent and transversely to one of the complementary flanges, between a release and an engage position. In the release position the latching member has clearance to allow passage of a corresponding one of the primary flanges. In the engage position the latching member blocks passage of the corresponding one of the primary flanges. Thus the latching member is operable to lock the coupling body on the glad hand body.
