ANTI-THEFT FIXING DEVICE FOR SECURING A WHEEL TO THE HUB OF A MOTOR VEHICLE.

摘要

Anti-theft fixing device for securing a wheel to the hub of a motor vehicle, comprising a threaded part (10) and a driving part that comprises a cylindrical head (2) and a sleeve-like insert (3) that has coupling indentations (35) on its exterior and that is force-fitted axially onto the cylindrical head (2) into a first use position, while being able to assume a second position in which it is engaged more deeply around the cylindrical head (2). The insert (3) is coupled rotationally to the cylindrical head (2) through friction means (32), the cylindrical head (2) and the insert (3) being configured in such a way that in the first position the friction means (32) are capable of transmitting a tightening or loosening torque, whereas in the second position these friction means (32) are not capable of transmitting this torque.
