Abstract
Air hose couplings for railway cars are prevented from uncoupling by wire form locking means reacting between the body of one coupling and the lip of the other coupling. In certain embodiments a wire form is an integral part of the air hose coupling assembly and has a laterally extending arm for manual unlocking. In another embodiment a detachable bifurcated wire form is applied to coupled air hose couplings after a train is made up and may be discarded when the respective cars are uncoupled. Alternatively, the detachable wire form also can be mounted on the clamp that secures the air hose to the coupling, or on a clamp that fits over the hose clamp, or mounted directly on the main body portion of a coupling.
