ABSTRACT:
The tensioning device for belts and the like comprises a supporting base (2), a winding reel (6) which can rotate relative to the base (2) about a respective axis of rotation (A1), a ring gear (13) which rotates integrally with the reel (6), an operating lever (14) for rotating the reel (6) in a first predetermined direction of rotation (S1) for winding the belt, a ratche mechanism (39), operating on the ring gear (13) and designed to prevent the reel (6) from rotating in a second direction of rotation (S2) opposite to the first predetermined direction (S1), the ratchet mechanism (39) comprising respective release means for allowing belt unwinding by reel (6) rotation in the second direction of rotation (S2). Further, the ratchet mechanism (39) comprises a first tooth (19) for engagement with the ring gear (13), the first tooth being designed to oscillate about two respective axis of oscillation (O1, O2).
