ABSTRACT:
A hose assembly including an elongated flexible metal hose attached to a hose fitting having a fitting body defining a passageway for conveying material. The fitting body has a mating portion for connecting the hose assembly to a corresponding fitting which delivers or accepts material passing through the hose assembly. A sleeve engages a surface of the fitting body and secures an end portion of the metal conduit to the fitting by trapping the end portion of the metal conduit between the sleeve and the fitting body. During installation, the sleeve is inserted into the body and subsequently the hose is inserted into a gap between the sleeve and fitting body. A fixture having a radially expanding member is slipped into the sleeve and brought into contact with the sleeve to deform the sleeve and consequently trap an end of the hose between the sleeve and the fitting.
