Security blocking system for preventing unauthorized use of fuel engine equipments, in particular of motor-vehicles e.g. cars, comprising a magnet valve (2) arranged in the fuel supply system of the engine, having a valve chamber (3) and an electromagnet controlled valve insert (4) for alternate interrupting of the fuel supply between a fuel feed pump (1) and the engine. In order to increase security of the blocking system and to provide a reliable operation the circuit of the magnet coil of said electromagnet (5) is provided with a control switch which is operatively combined with a security lock.
