ABSTRACT:
A connector for use with a plastic corrugated tubing is provided in which a first annular member is provided with an end face which is adjacent a projecting end of the tube when the annular member is disposed about the tube. The end face is disposed within a trough of one of the tube corrugations. An outer sleeve is threaded to the annular member and includes an inwardly depending flange having a face which is coextensive with the end face of the annular member. The two faces serve to clamp the projecting end of the conduit therebetween thereby clamping the connector to the conduit.
