摘要

A plug-in connector device (10) comprises a ring-like head portion (12) and a hollow shank (11). The shank (11) has locking balls (15) which can be held to project outwardly of the shank (11) in a locked condition of the device, and can also move to a retracted position under the control of an axially slidable probe (13), the movement of which is controlled by an actuator lever (20) 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.
