PROBLEM TO BE SOLVED: To reduce cost, and to facilitate inhibition of removal and release of the inhibition by employing a simple structure. SOLUTION: A release hole 4 is provided at an outer bead 3 of receiver inlet 2 side. An inner bead 6 and a stopper pawl 7 are provided at an insertion port 5 side. When the port 5 side is inserted into the inlet 2, an end 7a of the pawl 7 is engaged with the bead 3 to inhibit removal of the pawl 7. In the case of extracting it, a release pin 11 of a releasing jig 8 is forced from the hole 4 to remove the pawl 7. |
