    Abstract: A device is disclosed for locking the key ignition of a vehicle. The device includes braided cables encased in neoprene rubber, and a recess is provided at the midpoint of the length of these cables. A locking housing is basically cylindrical in shape and includes a combination lock in its center section while the ends of the housing are flared angularly outward and have two through holes which serve as receptacles for the cables. Finally, ratchet-like teeth are arranged along the length of the cable, and two spring loaded engagement levers are located in the cable receptacles within the housing. The cables fit around the steering column of a vehicle with the recess placed over the key ignition. The locking housing receives the cables in the through holes and is locked in place by the combination lock.
