ABSTRACT:
A female connector member for use in a quickly-attachable connector assembly with a male connector member comprises a housing formed with a socket for receiving the male connector member and further formed with a pair of circumferentially-spaced openings through a wall leading into said socket; and a locking member having a flexible arcuate section received on the outer face of the housing, and a pair of oblique locking elements normally projecting through the openings into the socket for locking the male connector member therein. The outer faces of the locking elements are inclined at an acute angle to the longitudinal axis of the socket and converge in the direction of the mouth of the socket, such as to facilitate the insertion of the male connector member into the socket by a small push force and to lock the male connector member against withdrawal from the socket even by a large pull force.
