ABSTRACT:
This invention provides a fluid fitting made up of telescoping sleeves providing an annular space therebetween adapted to receive the end of a tube. The outer sleeve is attached to the inner sleeve by being deflected around annular ridges at one end of the inner sleeve. The sleeves are attached to the tube by swaging the outer sleeve so as to grip the tube between the two sleeves. Grooves in the inner sleeve provide corners which dig into the inner surface of the tube and provide seals and retention, while recesses in the outer sleeve receive deflected material of the tube to prevent rotation.
