ABSTRACT:
A fitting or connecting corrugated tubing has a through opening and a liquid tight corrugated tubing connecting portion. The connecting portion has a shank to receive the corrugated tubing and a collar of greater diameter than the shank. The collar extends along the shank from a shoulder in the fitting and terminates before the end of the shank. Pawls in the connecting portion extend from the shank between the collar and the end of the shank. The pawls are hinged and have bevels and a bearing surface. The collar on the shank has an outside diameter slightly greater than the inside diameter of the corrugated tubing which renders the connector liquid tight when engaged with the corrugated tubing. The pawls resiliently extend to engage themselves in an inner corrugation of the corrugated tubing. Various pawl configurations engage the inside corrugations of corrugated tubing for a quick and firm liquid tight connection.
