A fitting (10) for attachment to a tube (12,14) by swaging comprises a cylindrical sleeve (16) having a tapered outer surface (18) and an inner surface (20) for receiving the tube (12, 14). A cylindrical swaging ring (22) having a tapered inner surface (50) engages the tapered outer surface (30) of the sleeve (16) such that the axial movement of the ring (22) in a forward direction with respect to the sleeve (16) causes the ring (22) to apply a radial force to the sleeve (16) to swage it to the tube (12, 14). The swaging ring (22) is comprised of a lightweight, high strength material, such as a composite material, and is locked onto the sleeve (16) both before and after swaging by one or more protrusions (66, 74, 76) on the outer surface (18) of the sleeve (16) which coopera- tively engage an annular groove (68, 78) in the swaging ring (22).
