Abstract

To prevent removal of laboratory or office equipment and the like, separate cables are attached to four or more items of such equipment and have circumferentially-grooved end members which are received in separate bores in a single lock body and are locked therein by a key-controlled keeper. Preferably, the keeper is a key-removable core inserted in a core chamber which partially intersects the cable-receiving bores, so that the core itself engages in the grooves of the cable end members to lock them against retraction. A mounting screw access passage traverses the core chamber, and is blocked by the core in such chamber to prevent access to a mounting screw inserted through such passage. In a modification, six cable-end receiving bores are circumferentially spaced about the lock body in a common plane. A rotatable keeper plate is mounted in the lock body in a parallel plane and has keeper lugs to engage cable end members inserted in such bores. A key-removable core blocks access to a mounting screw and operates as a lock to actuate the keeper plate.
