PROBLEM TO BE SOLVED: To reduce the weight and cost of a joint body and surely prevent slipping-out of a resin pipe by integrally forming the body of resin, and integrally forming the body and a fastener to fasten the pipe from the outside. SOLUTION: A straight joint 40 serving as a connection joint for a resin pipe is provided with a joint body 40a having an insertion part 41 with an O ring. A flange part for a fastener is integrally formed at a root portion of the insertion part 41. An opening for a pipe 42 is formed at the opposite side to the insertion part 41. A plurality of stepped portions 42b are provided at the outer periphery of the opening part 42. The body 40a is integrally formed from a resin material. A fastener 1 to fasten a heat medium circulation pipe 20 from the outer circumferential side is integrally formed with the body 40a. Namely, insertion formation is carried out such that an engaging piece 1a continuously provided to the fastner 1 is integrally embedded in the body 40a.
