ABSTRACT:
The rapid fastener is adapted to achieve a connection in the axial direction and in rotation of two elements and more particularly torque-transmitting shafts. It comprises at the end of one of the elements a socket (8) which is provided with at least one helical slot (14, 16) and on which is axially slidable a ring (18) defining at least one longitudinal slot which is laterally offset relative to the entrance (14) of the helical slot. The ring (18) is biased by a spring (24) toward the entrance of the socket (8). The second element has a stem (4) provided with a driving pin (6) which, in entering the helical slot, urges back the ring but is guided under the action of the spring (24) and the edges of the two slots toward the inner end of the helical slot and is then locked in this position without clearance.
