Claims

[Scope of utility model registration request]

A joint 2 connects the flexible pipe 2 arranged in the wall W and a terminal device such as a gas tank 1 connected to the pipe terminal part.
0, and by sandwiching the periphery of the opening H in the wall W between a mounting plate 6 attached to the outer surface of the wall W and a patch plate 4 attached to the back surface of the wall W. In a pipe end fixing device for fixing a pipe end to a wall surface W, the mounting plate 6 has a diameter larger than the opening H and a plurality of tongue pieces 61, 6 on the outer periphery.
1 is a protruding annular body, and these tongue pieces 61, 61 are arranged at a position away from the proximal end on the outer peripheral wall surface W side of the mounting plate 6, and protrude and retract from the outer peripheral surface of the mounting plate 6 in the radial direction. A protrusion 62 is provided which is always biased in the projecting direction, and a flange portion 12 is provided on the connection side end of the terminal device to protrude from the outer periphery of the connection port 11 for connecting the joint 20. An annular wall 13 that protrudes toward the wall surface W side and has an inner diameter slightly larger than the diameter including the tips of the tongue pieces 61, 61 is provided on the periphery of the annular wall.
61 are provided with engaging tongues 14, 14 that engage separately in the front-back direction, and apart from these, a radial protrusion 15 facing the projection 62 is formed, and this radial protrusion 15 A recess 16 is formed in the inner circumferential surface of the tongue pieces 61, 61, and when the rotational direction of the mounting plate 6 and the flange portion 12 of the terminal device are set to a constant posture in the fitted state, the tongue pieces 61, 61
A piping end fixture in which engaging tongues 14, 14 are located separately on the back side of the pipe, and a protrusion 62 protrudes into the recess 16.
