A connector includes a housing having a connecting portion, an insertion portion, and slits, and a retainer having arms, and engaging portions. The engaging portions are engaged with a flange portion of a first pipe member so as to retain the first pipe member. An inclinatory contact portion is provided between inner circumferential surfaces of the slits and outer surfaces of the, such that the pair of arms are urged in directions of approaching each other when a force to pull out the first pipe member from the insertion portion is exerted. |

1. A connector for connecting a first pipe member having a flange portion around an outer
circumference with a second pipe member, the connector comprising: a tube shaped housing having
a connecting portion, at one end thereof, formed to be connected with the second pipe member,an insertion portion, at the other end thereof, formed to be inserted with the first pipe member, anda pair of slits formed on a peripheral wall at a side of the insertion portion; and a arch shaped retainer having
a pair of arms formed to be inserted into the slits, and engaging portions inwardly protruding from the arms to enter into an inner circumference of the insertion portion of the housing and to be engaged with the flange portion of the first pipe member, thereby retaining the first pipe member,
wherein an inclinatory contact portion is provided between inner circumferential surfaces of the slits at a side of a first pipe member pull-out direction and outer surfaces of the arms at a side of the first pipe member pull-out direction, such that the pair of arms are urged in directions of approaching each other when a force to pull out the first pipe member from the insertion portion is exerted. |
