Abstract
Abstract A coupling and method of coupling thin-walled/tubing and the like includes an inner member and an outer member in the form of a sleeve or band surrounding the inner member 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, the tubing is forced into the tubing grooves, and by means of an annular ridge the tubing is pressed tightly against the seal in the seal receiving groove, thus forming a fluid-tight coupling member.

Claim 1
Independent Claim
192 words
A coupling for use with flexible hose, tubing and the like comprising: (a) a first member, (b) a second member surrounding said first member, (c) said members each having a tubing receiving end, (d) means for receiving and retaining tubing positioned between said members, said receiving and retaining means comprising: (1.) at least one first substantially annular tubing groove on one of said members, (2.) a substantially annular seal receiving groove on one of said members between said tubing receiving end and said one tubing groove, (3.) a first substantially annular, rounded ridge cooperating with the tubing and said tubing groove for forcing the tubing into said tubing groove without cutting or biting into the tubing, (4.) sealing means having a greater width than thickness and a width smaller than said sealing groove and about the same thickness as said sealing groove in said seal receiving groove, (5.) a second substantially annular means in the form of a substantially annular rounded ridge element on the other of said members cooperating with said tubing and said sealing means for exerting a force into said sealing means without cutting or biting into the tubing.
