Claims

[Claims for Utility Model Registration] The receptacle 2 at the end of the other fluid pipe to be connected is inserted into the receptacle 1 at the end of the other fluid pipe to be connected, and the connection is made watertight through the packing 4. On the inner surface of the detachment prevention fitting 6 that engages with the socket 1,
Alternatively, an appropriate number of wide locking piece accommodating recesses having a rectangular cross section are formed in the inner surface of the receptacle part 1 itself in the circumferential direction, facing the insertion opening 2, and inside the locking piece accommodating recess 7. The outer surface 12a has an arcuate shape with the apex closer to the rear surface 12d, and the inner surface has a width and a cross section that are substantially fitted into the locking piece housing recess 7. A locking piece 12 having a wide cutting edge 12c that substantially matches the outer peripheral surface of the insertion port 2 is housed, and includes a rear wall surface 7b of the locking piece accommodating recess 7 and a rear surface 12d of the locking piece 12. There is an elastic support piece 16 between
When the locking piece 12 is in its natural state, the locking piece 1
2 to the front wall surface 7 of the locking piece housing recess 7.
A push bolt 18 inserted into a screw hole 10 communicating with the accommodation recess 7 is inserted so as to press against the outer surface 12 of the locking piece 12.
a, and the locking piece 12 is pressed from the outer radial direction by rotationally tightening of the push bolt 18, and the cutting edge 12c of the locking piece 12 is pressed against the outer surface of the insertion part 2. A device for preventing separation of a fluid pipe, characterized in that the fluid pipe is wedged into the fluid pipe.
