Claims

[Claims for Utility Model Registration] (1) From the inlet side of the joint body toward the back, there is a first inner diameter portion, and a diameter smaller than the inner diameter of the first inner diameter portion and larger than the outer diameter of the pipe to be connected. An O-ring forming a second inner diameter part and extending from the back of the first inner diameter part toward the inlet side to seal the gap with the pipe, and a plurality of teeth formed in a disc shape and inclined toward the back on the inner surface. A lock collar in which the inner diameter of the teeth is smaller than the outer diameter of the tube, and the lock collar is formed to be expandable and contractible by cutting in the axial direction, and has an outer circumferential surface that increases in diameter toward the back and slopes toward the back. A lock ring having teeth on its inner circumferential surface, and a retainer having an inner circumferential surface whose diameter increases toward the rear so as to come into contact with the outer circumferential surface of the lock ring are attached in that order, and a means for preventing the retainer from coming off is provided. One-touch type pipe fitting. (2) From the back of the first inner diameter portion toward the entrance side,
2. The one-touch type pipe joint according to claim 1, wherein said lock collar, said O-ring, said lock ring, and said retainer are installed in that order. (3) The one-touch type pipe joint according to claim 1 or 2, wherein the retainer is formed integrally with the joint main body instead of the means for preventing the retainer from coming off. (4) From the back of the first inner diameter portion toward the entrance side,
After installing the lock collar, lock ring, retainer, and O-ring in that order,
2. The one-touch type pipe joint according to claim 1, further comprising a disc-shaped collar, and a means for preventing the collar from coming off.
