Abstract
Abstract An improved lock for preventing unauthorized removal of a nut. In one embodiment, a plate having a flange at one edge is locked in a housing. An integral nut and retainer are journaled in an aperture in the plate with the nut and retainer on opposite sides thereof. The nut is threaded on a stud and the housing locked in place to preclude access to the nut. In another embodiment, such as where a cable having a coupling member is to be protected, the plate has an aperture shaped to receive the coupling member. The plate is locked in a housing which has an aperture through which the cable passes.
