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.
Dispositif de fixation antivol de solidarisation d'une roue sur le moyeu d'un véhicule automobile, comportant une partie filetée (10) et une partie d'entraînement qui comprend un téton cylindrique (2) et un insert (3) en forme de manchon qui comporte extérieurement des empreintes d'accouplement (35), et qui est enfilé à force axialement sur le téton cylindrique (2) en sorte de prendre une première position d'utilisation, tout en étant susceptible de prendre une seconde position où il est engagé plus profondément autour du téton cylindrique (2). L' insert (3) est lié en rotation au téton cylindrique (2) au travers de moyens de friction (32), le téton cylindrique (2) et l'insert (3) étant configurés en sorte que dans la première position, les moyens de friction (32) sont aptes à permettre d'assurer la transmission d'un couple de serrage ou de desserrage, tandis que dans la seconde position, ces moyens de friction (32) sont inaptes à permettre la transmission de ce couple.
