Improved alarm for motor vehicles, characterized in that it is constituted by an optical and/or acoustic signal emitter, which is housed inside the vehicle conveniently connected to its battery, and equipped with a multiple switch device, arranged so that the circuit electric is open when all the doors, bonnet and trunk of the car remain closed, while the opening of any of them, causes the closure of said circuit and the subsequent operation of the transmitter, whose signals are detected by a properly adapted receiver to the frequency of the transmitter, and provided with a switch for its stoppage or start-up at the user's will, which will carry it in the convenient place to easily perceive the signals emitted.
