PROBLEM TO BE SOLVED: To provide a confirmation device capable of preventing a pseudo- coupling between a retainer and a pipe and using a connector itself as it is without requiring a special design. SOLUTION: This confirmation device 60 comprises a C-type member 61 seated on an end face 33 of the retainer 30, a ring member 62 which is inserted into the retainer 30 and has a seated spool 42 of the pipe 40 and a connecting member 63 connecting the C-type member 61 and the ring member 62 each other and having a formed weak point part 64 on the part. When the pipe 40 is inserted into the retainer 30 till the spool 42 of the pipe 40 is located at the depth by a pawl part 32 of at least of the retainer 30, the weak point part 64 of the connecting member 63 is ruptured by force generated by pushing the ring member 62 by the spool 42 of the pipe 40 seated on the ring member 62. |
