A connector comprises first and second tubular couplers (3, 5) and a tubular locking collar (7), the locking collar comprising at least one radially extending locking rib (47, 49) comprising longitudinally opposed locking faces. Each coupler is formed with a respective locking formation (15), the connector being arranged such that each coupler can be mated together such that each locking formation is adjacent a respective one of the locking faces of the locking rib. Rotation of the collar (7) relative to the couplers (3, 5) is operative to cause each locking formation to engage with a respective locking face to lock the couplers together such that relative movement between each coupler and the collar along the longitudinal axis is resisted. Thus the collar and couplers are arranged when locked together to prevent relative rotation between the couplers, and also to prevent relative longitudinal movement between the couplers. |
