ABSTRACT:
A coupling and method of coupling thin-walled/tubing and the like includes an inner member, an intermediate wedge member and an outer member in the form of a sleeve surrounding the intermediate and inner members with the tubing therebetween. The inner member is provided with a pair of tubing grooves and a seal receiving groove between the two tubing grooves or at least between one groove and the tube receiving end of the coupling. By means of annular ridges on the intermediate wedge member the tubing is forced into the tubing grooves, and by means of an annular ridge on the wedge the tubing is pressed tightly against the seal in the seal receiving groove, thus forming a fluid-tight coupling member.
