A demountable junction for tubular members is described and is formed as follows. A first tubular member (2) has a circumferential groove (4) in an external wall. A second tubular member (3) has a plurality of circumferential slots (9) therein and an open end which receives the first tubular member in sliding engagement. A circlip (6) is formed from a resilient material and includes a plurality of peripherally disposed inwardly extending segments (5). The segments (5) are received in the slots (9) in the second tubular member (3) and in the groove (4) in the first tubular member (2) when the slots (9) and the groove (4) are in register. An 'O'ring (8) forms a seal between the first and second tubular members. Such a junction is simple to manufacture and allows the tubular members to rotate relative to one another when the two are coupled together.
