Abstract
In a device for reversibly locking a constant-velocity joint (2) with respect to a hub (1), the constant-velocity joint is axially locked to the hub by means of a spring-lock ring (21) of circular cross section recessed in a circumferential groove (22) in part formed on said joint (2) and in part on said hub (1). The joint comprises reaction means (24) integral therewith, particularly a rigid annular diaphragm disposed adjacent to the hub and facing an axial through bore (15) formed in the hub. The diaphragm is adapted for co-operation with an extraction tool (28) that can be inserted through the hub bore (15) in order to apply to the joint (2) and the spring-lock ring (21) an axial force with relative to the hub in either direction so as to separate or couple the joint (2) from or to the hub.
