摘要： PROBLEM TO BE SOLVED: To provide a pipe connection member having a main body connected with a pipe member to be connected, an engaging part provided with a claw part engageable with an engaged part of the pipe member, and an elastic connection part for connecting the engaging part with a side face of the main body and connecting the claw part so as to displace between a first condition in which it is engaged with the engaged part and a second condition in which the engagement is released to hold the engagement property of the pipe member with the engaged part even when large pulling-out force is applied on the pipe connection member. SOLUTION: A regulation member 12 for regulating swing and displacement of the elastic connection part 9 onto a claw part 8a side is provided among a face opposing to the claw part 8a in the elastic connection part 9, the main body 7, and the engaging part 8.
