A connector for establishing connection between pipes has an end portion of a maximum diameter which permits insertion of the connector in the pipe, and close to its end an anchoring portion of smaller diameter than the maximum diameter, an arched portion between the anchoring portion and the end, and a connecting portion which extends from the anchoring portion on the side thereof facing away from the pipe end obliquely upwardly to the maximum diameter of the connector. A lip seal of U-shaped cross-section is clamped about the anchoring portion to seal between the outer side of the connector and the inner side of the pipe. Upon insertion of the connector in the pipe the lip seal U-flange closest to the pipe end is bent over the U-web and the lip seal U-flange distant from the pipe end is bent over the connecting portion, while upon reversed relative movement of the connector the lip seal U-flange closest to the end is bent over the arched portion and the lip seal U-flange distant from the end is bent over the U-web.
