A plug-in connector device comprises a ring-like head portion and a hollow shank. The shank has locking balls which can be held to project outwardly of the shank in a locked condition of the device, and can also move to a retracted position under the control of an axially slidable probe, the movement of which is controlled by an actuator lever on the head portion which can only be moved to release the locking balls from their locked condition on a separate manipulation of a second lever, or in other embodiments a safety catch button, also mounted on the head portion.
