The present invention provides a connector arrangement for connecting and locking tubular members. The connector consists of two tubular members (100, 110) and a coupling member. The tubular members are threaded together to create a threaded connection. The locking arrangement is provided by a pathw ay (120, 130) formed on the tubular member whereby a locking member (500) can b e inserted in to the pathway to lock the threaded connection. The locking arrangement may also be provided by a plurality of castellation members (614 , 714) disposed on each tubular member. The connector may also have a separate coupling member (620) which has opposite right-hand (622R) and left-hand (622L) threaded ends to threadedly mate with the threads of the two tubular members.
