A connector has a coupling nut rotatable on a body and lockable by means of a locking ring mounted on the nut. When slid axially to its locking position, the locking ring engages splines on both the nut and the body to prevent relative rotation. A circular spring carried in a groove on the nut engages behind a vertical wall on the inner surface of the locking ring to prevent the locking ring being unlocked. The locking ring is unlocked by pushing a release ring axially into the locking ring so that a ramp surface on the release ring pushes the spring in and allows the locking ring to be slid back.
