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.

A rapid fastener of the bayonet type for connection of two elements, comprising a socket terminating the first element, a stem terminating the second element, the socket having an open end for receiving a stem, a laterally projecting pin on the outer surface of said stem, a slot in the socket, said slot having an open entrance end for the entrance of said projecting pin, guiding and locking means comprising a ring axially slidable along the socket but rotating with said socket, spring means for biasing said ring toward the open end of said socket, a longitudinal slot formed in said ring and having an open end toward the open end of the socket, and two lateral walls progressively diverging toward said open end of the longitudinal slot; said longitudinal slot open end being laterally offset relative to said open entrance end of the socket slot and having an end edge which partly closes said entrance end of the socket slot and which is urged back by the pin as the stem penetrates in said socket, said socket slot having an helical shape which causes helical relative motion of said penetrating stem and said socket and guides the pin to the entrance end of the longitudinal slot so that the end edge of said longitudinal slot is released and the ring is biased to a locking position in which the pin is trapped by edges of the two slots.
