Abstract
A method and apparatus are disclosed for coupling a flexible hose to a metal tube. A metal reinforcing sleeve is placed over the outside of the tube, and a metal collar is placed over the outside of the reinforcing sleeve. The tube and reinforcing sleeve and collar are secured together by simultaneously bumping the tube and reinforcing sleeve to form, in a single operation, radially outwardly projecting beads on the tube and reinforcing sleeve on each side of the collar.
