Anti-theft auxiliary lock for vehicles

An anti-theft door lock for vehicles in which a vehicle door is secured in a closed position within a door frame by means of a striker projecting from the door frame, the striker being aligned with a parting line between the vehicle door and the door frame, the anti-theft lock comprising:

• a base plate for straddling the vehicle door and the door frame, the base plate having an opening for registration with the parting line adjacent the striker;
• a cover plate for securement over the base plate, the cover plate including a cover portion for overlying a corresponding portion of the base plate;
• a locking cable, the locking cable being slender for fitting between the vehicle door and the door frame, and including an anchoring portion for anchoring the locking cable to the striker;
• a first capturing element on the locking cable and spaced from the anchoring portion for passing through the opening in the base plate when the anchoring portion is anchored to the striker;
• a second capturing element adjacent the opening in the base plate, the second capturing element being complementary to the first capturing element for cooperating with the first capturing element to selectively detachably capture a further portion of the locking cable between the cover portion of the cover plate and the corresponding portion of the base plate, and securing the base plate in place straddling the parting line between the vehicle door and the door frame when the cover plate is secured over the base plate;
• and
• a lock for locking the cover plate in place over the base plate and precluding unauthorized access to the first and second capturing elements and the anchoring portion of the locking cable so as to maintain the base plate in place straddling the parting line between the vehicle door and the door frame and secure the vehicle door in the closed position against unauthorized opening.
