ABSTRACT:
A lock device comprises a cylindrical container securable by split clamps to the frame of a device, and is adapted to store a case-hardened chain. The container has "pass-and-catch" notches at one end for receiving penultimate links of the chain, when the chain is used to lock a device. The container is closed by a lockable cap, which closes the upper ends of the notches to anchor the chain ends. The entire accessible portion of the structure, including the clamps, the container, the cap, and the chain, is of case-hardened steel. The clamps are secured to the container by tamper proof fastening elements. A preferred embodiment includes a container and a lockable cap having splining tongs formed from the rim portion thereof, and has clamps secured to a bicycle post by tamper proof bolts. The rim of the container is bent over at opposite sides to form keeper portions under which ends of a lock-controlled latching bar may be moved.
