Anti-theft fixing device (1) for securing a wheel to the hub of a motor vehicle, including a threaded distal portion (2), a holding portion (3) intended to be applied against the rim (6) of the wheel to be fixed, and a proximal driving portion (4) intended to be inserted into a well (61) of said rim (6), and which permits the transmission to said threaded portion (2) of a clamping or unclamping torque through a key or the like, the coupling of the key or the like (5) with said driving portion (4) being brought about through matching indentations (41, 42). The proximal driving portion (4) is chosen to have a diameter close to the inside diameter of said well (61). The indentations (41, 42) in the proximal driving portion (4) are provided on the periphery of the latter so as to be disposed facing the inner wall (62) of the well (61) when the fixing device (1) is in position holding the wheel, and they have a small depth. The proximal driving part (4) is surmounted by an element (7) which covers it and which is able to pivot freely and axially thereon. |
