ABSTRACT:
A coupling assembly is disclosed that includes a first member and a second member having a receiving portion sized to receive the first member. A retaining formation is provided on one of the first and second members. The retaining formation includes a ramp and two or more grooves, wherein each groove is at least partially defined by converging surfaces. A locking member is moveably secured in a cavity in the other of the first and second members. The locking member is configured to be moved in a first radial direction by the ramp upon movement of the first member into the second member. The locking member is also biased in a second radial direction opposite the first radial direction into a groove in the retaining formation to become positioned between a converging surface on the retaining formation and the cavity upon further movement of the first member into the receiving portion of the second member, and may be progressively received in additional grooves on the retaining formation if the first member is further inserted into the second member.
