ABSTRACT:
A connector for connecting a small diameter pipe is disclosed. The connector comprises a joint body formed with an insertion bore for a conduit and having large, intermediate and small diameter portions, the intermediate diameter portion being fitted with a seal ring, and a ring-like holder provided with a pair of elastic pawls engaging with an opening of the large diameter portion. When inserting the conduit into the insertion bore, the conduit fits to the seal ring, while holder pawls engage with an annular protrudent wall of the conduit, thus positioning the conduit and preventing its removal. The connector also includes a ring-like confirmative member provided with a pair of elastic pawls capable of engaging with grooves of the holder pawls. The positions of confirmative member pawls are determined between the holder pawls and the opening wall. The confirmative member further includes elastic deformable pieces formed on the pawls or on the ring thereof, corresponding to projections provided on the joint body.
