<p>PROBLEM TO BE SOLVED: To prevent slip-off of a pipe by integratedly forming a fastening part on the opening end part of the receiving port part of a joint for inserting a pipe end part to fasten an inner surface to a pipe outer surface, and arranging a fastening cam member for fastening a fastening part. SOLUTION: Then end part of a pipe 3 is inserted in the receiving port part 4 of a joint. A set pin 30 is inserted from an end part buried a lock head part 30a through respective shaft holes 24, 25, from the outer surface of a rib 22 toward the outer surface of a rib 23. A cam lever 28 is rotatably operated so as to make a first cam surface 32 abut on the outer surface of a movable rib 22, a lock head part 30a is rotated on the outer side of a fixing rib 23, and it is projected transverse to the set pin 30. The cam lever 28 is rotatably operated so as to make a third cam surface 34 abut on the outer surface of the movable rib 22, the movable rib 22 is approached to the fixing rib 23, a band 21 is fastened so as to contract the diameter of the receiving port part 4, and the pipe 3 is prevented from being slipped off and the rotation thereof is locked.</p> |
