A connection device comprises a lock component of non-circular cross-sectional shape, the lock component being both angularly and axially moveable relative to a housing, stop means operable to limit angular movement of the lock component relative to the housing, the lock component having a threaded drive region, and a drive nut in threaded engagement with the drive region, wherein angular movement of the drive nut relative to the housing when the stop means are not engaged is able to drive the lock component for angular movement, rotation of the drive nut when the stop means are engaged causing axial displacement of the lock component relative to the housing.
