Abstract: A device used to restrain the flying or whipping of hoses that are accidentally detached while under pressure. The device is formed of a cable halter having slip knot type snares at each of the extremities for engagement about the hoses at a position on both sides of the expected place of separation, a pair of springs forcing the snares to close, so as to obtain a tight engagement with the hoses, and a safety fastener adapted to lock together the hose connectors. The safety fastener is connected to the cable halter by means of a secondary cable, which encircles the hoses to keep the halter cable close to the hoses.
