TUBE COUPLING LOCKING DEVICE

摘要

A locking assembly for preventing undesired loosening of a made-up coupling includes a cooperating pair of rigid lock members that encircle about a coupling nut with one of the lock members having an end connected to a second cooperating coupling nut or the body of an associated fluid device. The cooperating lock members are arranged to prevent relative rotation between the encircled coupling nut and the cooperating coupling nut or associated fluid device.
