摘要： PROBLEM TO BE SOLVED: To smoothly perform connection work.
SOLUTION: In a plug-in joint 1 for a corrugated pipe, the corrugated pipe T is inserted into a joint body 10 from a retainer pushing sleeve 50 inner hole, and respective pins 73 are elastically deformed and bent to the inner side when an annular protrusion T' is abutted to the respective pins 73 (pin group) of a stopper 70. At that time, respective split circumferential pieces 75 with which at least a part of a root part of the respective pins 73 is brought into contact is deformed at a root of a ring part 71, and is opened to the outer side. When the annular protrusion T' gets over the inner side of the stopper 70, the pin group of the stopper 70 and the respective split circumferential pieces 75 are recovered to the original state. When the pin group is elastically deformed and recovered to the original state, a worker inserting the corrugated pipe T can feel passing feeling by the sound and/or the touch, and can confirm that the annular protrusion T' passes the stopper 70 by the passing feeling. After the annular protrusion T' gets over the pin group, an outer side of an annular recess T" is surrounded by the stopper 70, and the pin group goes into the annular recess T" and the corrugated pipe is prevented from slipping out until it is fixed.
