Abstract
A cable lock device is set forth. In one embodiment, a soft metal housing is constructed having an internal cavity for locking on the dead end of the cable. The cable is extended from the housing in a bight and the free end of the cable is inserted through a pair of aligned openings in said housing. The free end of the cable is immediately adjacent to a locking surface and is forced against that surface by a spring loaded rotatable disk. The locking surface incorporates a pair of parallel sharp edges wherein said edges are jammed against the cable, and/or deformed because the cable is made of harder material. In another aspect, the cable on insertion, dislodges a sacrificial U-shaped bracket to enable the cable to get past the disk. A relatively strong spring bears against the cable to enable firm backing, and the spring force is sufficiently strong that disk movement is assisted by the bracket to enable initial cable insertion.
