ABSTRACT:
An anti-theft device for a vehicle whereby when the driver sets the correct combination on two knobs on a dashboard casing, he switches off the circuit supplying electrical power to the ignition device. In addition, by so doing the driver also switches on an anti-theft device which causes the emission of an alarm signal in the event of a thief attempting to short-circuit the power switch, or open the engine hood, or the lid of the luggage trunk, or any door of the vehicle. The anti-theft device does not require any switch key.
