An anti-loosening device (1) for a fastening unit (2) of a motor-vehicle wheel (W) is described here, wherein the motor-vehicle wheel (W) is configured to be coupled with a wheel hub (H) by means of the fastening unit (2). The anti-loosening device (1) is configured to be arranged within the wheel hub (H) along an axial direction, so that a main axis of the anti-loosening device (1) coincides with the wheel axis (W).The anti-loosening device (1) comprises:- a gear (3) arranged to cooperate with inner teeth (H3) of the wheel hub (H),- an elastic element (5) extending axially with respect to the gear (3), and- a coupling element (8) obtained on a sector of said gear (3), arranged to receive a corresponding fastening member (10),During assembly of the wheel (W) - hub (H) assembly, the anti-loosening device (1) is arranged to create a compressed configuration, wherein the gear (3) is decoupled with respect to the inner teeth (H3), and is arranged within a cavity portion (16) obtained on the inner surface (H2) of the wheel hub (H), so as to allow rotation of the anti-loosening device (1) around the main axis;Following a rotation of the anti-loosening device (1), the coupling element (8) is arranged to be radially aligned with respect to an anti-rotation sector (9) obtained on the fastening unit (2), in such a way that in the final assembled condition, the fastening member (10) coupled to the coupling element (8) cooperates with the anti-rotation sector (9), to avoid loosening of the locking unit (2).
