Claim 0:
1. A method for coupling a fitting to a tube end comprising:
inserting the fitting to the tube end wherein a portion of the tube surrounding the fitting comprises an outer surface that reduces in diameter in a direction toward the end; and
pressing a collar over said outer surface of said tube with a predetermined axial load causing a tapered inner surface of said collar to engage said tube outer surface, wherein said predetermined axial load positions the collar at a location over the tube for providing sufficient radial pressure on the tube against the fitting forming a connection between the tube and the fitting such that a sufficient axial load on the tube in an axial direction away from the fitting will cause the tube to fail before said connection fails.
