The end portion 2 and the chambers 3' and 3 are coaxially connected with one another. The large-diameter chamber 3 is surrounded by a wall having a pair of window openings 9, and a pair of resilient arms 7 each lying in one of the window openings 9 and having a radially inwardly bent pawl 5. The small-diameter chamber 3' contains seal rings 6, a bush 12 and a sleeve 13 positioned on the opposite side of the seal rings from the bush, which are all fitted about a pipe P connected in the main body 1. The large-diameter chamber 3 contains a cylindrical holding member 8 having an inner surface portion engaged with a wall portion of the pipe P, and an outer surface having a shoulder against which the pawls 5 are held.
