Abstract: An antitheft gear lever lock for cars comprising a bracket (1) forged by manganese steel under solubilized state having a Brinell hardness of approximately 220 kg/mm.sup.2. The bracket is formed with an end section (2) provided with throughholes (3) for fastening bolts (12) and being able to be subjected to one or more bendings (8). The bracket (1) has further an elongated intermediate section (6) provided with one or more bendings (8', 8") approaching the gear lever (14) and has a head section (4) provided with holes (5) for the connection to the antitheft padlock closure mechanism (16) which is supported by the bracket (1). The antitheft padlock closure mechanism is adapted to lock a gear lever (14) by a bend (28) embracing and retaining the gear lever (14) in the operative position and the bend (28) is able to reach its rest position by an easy rotational movement.
