A connection device is described which comprises a male member (12) which may be received in a female socket member (13). Cam means (30) is journaled in an eccentric cam follower surface (34) in the socket (13) for rotation about a second axis displaced from the axis of the socket (13). Means, preferably a fluid member (17), is provided for rotating the cam means in first and second opposite directions so that when the abutment surface (21) of the male member (12) is received in an aperture (38) in the cam means and the cam means is rotated in the first direction, a locking surface (41) of the cam means (30) is moved radially inwardly and in a longitudinal direction away from the entrance of the socket to engage the abutment surface (21) to lock the male member in the socket. Subsequent rotation of the cam means (30) in the opposite direction releases the engagement. An expelling surface (42) may be provided on the cam means to aid in expelling the male member from the socket, preferably by engaging an expulsion surface (22) provided on the male member (12). |
