Concentric hose coupling with cuff assembly surrounding an end of the outer hose

In a hose assembly having opposite ends and having a first fluid passage therein for conveying a volatile liquid fuel in one direction from one of said ends thereof to a container adjacent the other of said ends thereof and a second fluid passage therein for returning the vapors of the volatile liquid fuel from the container to said one end thereof, the assembly comprising a flexible inner hose having an outer peripheral surface and defining one of said fluid passages therein, a flexible outer hose having an inner peripheral surface and an outer peripheral surface and being disposed around said inner hose, said inner peripheral surface of said outer hose and said outer peripheral surface of said inner hose defining the other of said fluid passages therebetween, said outer hose comprising a corrugated tube that has the corrugations thereof extending throughout the entire length thereof, and a polymeric cuff secured to one of said ends of said outer hose, the improvement wherein said cuff has inner and outer parts that respectively cover said inner peripheral surface and said outer peripheral surface of that end of said outer hose that is secured thereto so that a metallic coupling structure can be adapted to be secured to said cuff at said inner and outer parts thereof, said cuff having an outer end edge means and an inner end edge means, said outer hose extending through said inner edge means of said cuff to said outer edge means thereof.
