ABSTRACT:
A connector interposed between a small-diameter metallic pipe with a collar end wall and a flexible hose to connect them comprises a joint and a retainer. The joint is formed with a through hole extending in the axial direction thereof, and has a protrusion wall and two cylindrical walls projecting therefrom on either side. One cylindrical wall has a sealing member fitted in an annular groove formed in the periphery thereof. The retainer has an engaging wall formed with an opening adapted to be engaged with the one cylindrical wall, and a plurality of elastic arm walls with click walls extending from the engaging wall in the axial direction. In use, the one cylindrical wall is inserted in the metallic pipe, the other cylindrical wall is inserted in the flexible hose, and the collar end wall and the protrusion wall are resiliently clamped between the engaging wall and the click walls.
