A connector assembly for a length of corrugated tube, the connector assembly being predominantly cylindrical and comprising: a fitting including a passage; a frusto-conical clamping surface located on interior walls of the fitting; a seal (105; 120) at or adjacent to the frusto-conical clamping surface; and an axial loading means operably connectable to the fitting, the axial loading means including a collet and a nut which is engageable with the collet, the collet in use being engagable with at least one corrugation of the corrugated tube by which the corrugated tube is caused to move with the collet, wherein proximal and distal ends (108, 106) of the collet include a same frusto-conical profile which opposes and is matingly engagable with the frusto-conical profile of the clamping surface, the clamping surface tapers radially outwardly and forms a shoulder against which, in use, the corrugated tube abuts, such that the collet can be oriented with either the proximal or distal end (108, 106) proximate to the clamping surface to matingly engage with the frusto-conical profile of the clamping surface, wherein, the connector assembly is arranged such that in use when the corrugated tube is in fluid communication with said passage of said fitting, axial movement of said axial loading means towards said clamping surface clamps said corrugated tube between said frusto-conical clamping surface and the frusto-conical profile of the collet as well as against said seal (105; 120) wherein 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 (105; 120) and sealed thereagainst under the action of the axial loading means. a fitting including a passage; a frusto-conical clamping surface located on interior walls of the fitting; a seal (105; 120) at or adjacent to the frusto-conical clamping surface; and an axial loading means operably connectable to the fitting, the axial loading means including a collet and a nut which is engageable with the collet, the collet in use being engagable with at least one corrugation of the corrugated tube by which the corrugated tube is caused to move with the collet, wherein proximal and distal ends (108, 106) of the collet include a same frusto-conical profile which opposes and is matingly engagable with the frusto-conical profile of the clamping surface, the clamping surface tapers radially outwardly and forms a shoulder against which, in use, the corrugated tube abuts, such that the collet can be oriented with either the proximal or distal end (108, 106) proximate to the clamping surface to matingly engage with the frusto-conical profile of the clamping surface, wherein, the connector assembly is arranged such that in use when the corrugated tube is in fluid communication with said passage of said fitting, axial movement of said axial loading means towards said clamping surface clamps said corrugated tube between said frusto-conical clamping surface and the frusto-conical profile of the collet as well as against said seal (105; 120) wherein 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 (105; 120) and sealed thereagainst under the action of the axial loading means.
