A joint for a resin pipe, which is provided with a tightening sleeve 6 which, when fitted into the outer peripheral surface of the cylindrical part 4, clamps the resin pipe 5 against the outer circumferential surface of the cylindrical part 4 to prevent it from coming out. 2 The tightening sleeve 6 is attached to the outer peripheral surface of the cylindrical portion 4.
The joint for a resin pipe according to claim 1, which is a registered utility model, and has a projection 7 that is cut into the inner circumferential surface of the resin pipe 5 when the resin pipe 5 is fitted. 3. The insertion depth is defined by contacting the outer circumferential surface of the longitudinally intermediate portion of the cylindrical portion 4 with the end edge of the resin tube 5, and the insertion depth is determined by the insertion force accompanying the fitting of the tightening sleeve 6. 5. The resin pipe joint according to claim 1 or 2, in which a stepped portion 8a is formed to allow the user to climb over the resin pipe. 4 An engaging portion between the joint body 3 and the tightening sleeve 6 that automatically engages when the fitting operation of the tightening sleeve 6 is completed and acts to prevent the tightening sleeve 6 from coming off. 10a, 10
2. The resin pipe joint according to claim 1 or 2 of the utility model registration claim, which has a shape of b. 5. An annular recess 11 is formed on the inner circumference of the tightening sleeve 6 to absorb the deflection of the resin pipe 5 toward the outer circumference that occurs when the tightening sleeve 6 is fitted. The resin pipe joint according to item 1 or 2. 6. The length relationship between the tightening sleeve 6 and the cylindrical portion 4 is adjusted such that the tip of the cylindrical portion 4 is located at a longitudinally intermediate portion of the tightening sleeve 6 when the fitting of the tightening sleeve 6 is completed. A resin pipe joint according to claim 1 or 2 of the utility model registration claim. The brief description of the drawing has been amended as follows. In the 6th line of page 13 of the specification, "perspective part" will be corrected to "perspective view." On page 13, line 12 of the specification, “1... joint body,
" should be corrected to "3...Joint body".
