A connector for connecting a small diameter pipe is disclosed, the arrangement being such that: a joint body formed with an insertion bore for a pipe has large, intermediate and small diameter portions; a seal ring is attached to the intermediate diameter portion; and a holder including a pair of elastic stoppers is set in an opening formed in the large diameter portion, the stoppers engaging with a swelling wall shaped on the pipe circumference, thus positioning the pipe and preventing its removal. The connector further includes a confirmative member which is stopped in the opening when the pipe is in the proper connecting position to the joint body. The confirmative member comprises a securing wall provided at the tips with stopping pawls and having a pair of arms. The confirmative member is disengaged from the opening on the basis of a positional correlation between the swelling wall or elastic stoppers and the securing wall when the pipe is properly installed. Whereas in an ill-installed state, the engagement of confirmative member can not be released.
