PROBLEM TO BE SOLVED: To ensure sufficient sealing performance by certainly caulking a corrugated pipe, in a joint device for a corrugated pipe. SOLUTION: In this joint device for the corrugated pipe, an annular sealant 27 is arranged inside of a cylindrical joint body 11. The corrugated pipe 18 is inserted inside of the joint body 11. The end of the corrugated pipe 18 is caulked to be crashed in a pipe axial direction between a pressing ring 23 inserted inside of the joint body 11 and a stepped portion 16 formed inside of the joint body 11, thereby a seal portion 26 brought into contact with the sealant 27 by being pressed by the pressing ring 23 is formed at the end of the corrugated pipe 18. The sealant 27 and the end of the corrugate pipe 18 before caulked by the pressing ring 23 are so configured that they are not brought into contact with each other. COPYRIGHT: (C)2009,JPO&INPIT
