ABSTRACT:
A tee connector for coupling a corrugated tubing lateral normal to a larger diameter corrugated tubing main with a circular aperture in its side wall. The connector has a first end with a circular periphery sized to be received in the aperture. The first end is configured with two arcuate longitudinal recesses separated by two arcuate protuberances to conform with the interior surface of the main. Adjacent the first end are positioning projections which abut the exterior surface of the main to position the connector normal to the main. Also, adjacent the first end are tabs which are snapped through the aperture to engage the interior surface of the main. The lateral is received in a bore in the second end. The length that is received is limited by limiting projections in the bore adjacent the first end. Detents on the interior surface of the bore engage the corrugations of the lateral to inhibit its removal from the connector.
