ABSTRACT:
A system for removably and mechanically locking a sleeve on a driveshaft includes at least one peripheral groove comprising a bearing face on the driveshaft. At least one peripheral slot on the sleeve forms a chamber in the internal peripheral wall of the sleeve and includes a bearing face. At least one wedge-forming element can move more or less radially within the chamber between a position retracted inside the housing to allow the shaft to be slipped into the sleeve, and a position partially protruding from said chamber in which said element is designed to bear on the bearing face of the groove and on the bearing face of the chamber 34. Means for moving the movable wedge-forming element move the wedge-forming element radially inward, from outside the sleeve, in order to lock the sleeve on the shaft.
