Abstract: A vehicle anti-theft device including a gear shifter locking device for enclosing the handle of a vehicle gear shifter therein to prevent the usual shifting of the gear shifter, and a steering wheel locking device to prevent or limit the usual turning of the vehicle steering wheel. The gear shifter locking device includes two mating housing parts for enclosing the gear shifter handle therein, and a bar connecting the housing parts together, one bar end portion being slideably secured to one housing part, and the other housing part being rotatably secured to the opposite bar end portion. A locking mechanism coacts with the bar to lock the housing parts together. A coil spring is tensioned against the bar so that the two housing parts automatically separate apart from each other when unlocked by a key-operated lock mounted on one housing part. The housing parts can be provided with downwardly extending skirt portions to enclose the handle-carrying rod portion of the gear shifter.
