PROBLEM TO BE SOLVED: To improve workability by providing a stopper member protruded or retracted in a communication path at the tip of an insertion section at the other end of a male member, and protrudably and retractably providing a stopper member facing the stopper member of the male member on the communication path at the junction of the male member. SOLUTION: A male member 1 connected to a female member 2 covers the recessed groove 3a of a main body 3 with a cover plate 4 to form a communication path. A stopper member 11 protrudable/retractable with the tip 11a is pivotally fitted to the recessed step section 8a of an insertion section 8. When the female member 2 is separated, the stopper member 11 prevents the drop of pierce nuts with a spring 9 fitted between its recess and the ceiling face of the recessed step section 8a. A stopper member 27 covered on its opening by a press cover 23 is fitted to the upper section of the male member junction 21 of a main body 20. When the male member 1 is separated, a tip 27a is protruded by a spring 26 fitted between the press cover 23 and the recess of the stopper member 27 to prevent the drop of pierce nuts from the tip opening of the nut transportation pipe 28 of the female member 2. |
