Claim Text:
1. A connector assembly for a length of corrugated tubing, the connector assembly comprising: a fitting including a passage; a frusto-conical clamping surface; a seal at the frusto-conical clamping surface; and an axial loading element operably connectable to the fitting, the axial loading element including a collet engagable with at least one corrugation of a corrugated tube by which the corrugated tube is caused to move with the collet, wherein proximal and distal ends of the collet include a same frusto-conical profile matching the frusto-conical profile of the clamping surface, such that the collet can be oriented with either the proximal or distal end proximate to the clamping surface, wherein, a corrugated tube is in fluid communication with said passage of said fitting, axial movement of said axial loading element towards said clamping surface clamps said corrugated tube between said frusto-conical clamping surface and the frusto-conical profile of the collet as against said seal whereby said corrugated tube is thereby sealingly restrained to said fitting; and wherein the frusto-conical clamping surface is formed such that it causes an end portion of the corrugated tube to form a flare by said end portion being compressed against said frusto-conical clamping surface and against said seal and sealed thereagainst under the action of the axial loading element.
