ABSTRACT:
A releasable connector (3) is described for connecting a first member (2) to a second member (1), the members (1, 2) being adapted to be inserted into one another. The releasable connector (3) comprises a lock element (4) located in a recess (5) in a surface of the first member (2) and biasing means is provided to bias the lock element (4) to a first position in which the lock element (4) extends from the recess (5) to engage a shoulder on the second member (1) to lock the first member (2) to the second member (1) against withdrawal. A movable release device (7) is located on the second member (1) so that actuation of the release device (7) causes the release device (7) to co-operate with a surface (9) of the lock element (4) to move the lock element (4) to a second position against the action of the biasing means. This causes the lock element (4) to be disengaged from the shoulder on the second member (1) with the release device (4) terminating short of the recess (5) in the first member (2). The arrangement is such that during withdrawal of the members (1, 2) from each other the lock element (4) moves to a third position in which the lock element (4) is further into the recess (5) than in the second position.
