A hose assembly, clip means therefor and method of making the same are provided, the hose assembly having fluid passages therein for respectively conveying a volatile liquid in one direction to a container and returning the vapors of the volatile liquid from the container, the assembly comprising a flexible inner hose having an outer peripheral surface and defining an inner one of the passages, a flexible outer hose having an inner peripheral surface and being disposed around said inner hose, the inner peripheral surface of the outer hose and the outer peripheral surface of the inner hose defining an outer one of the passages, a coupling fixed to one end portion of the outer hose, a tubular fitting fixed to an end portion of the inner hose, and a clip holding the fitting and the end portion of the inner hose substantially concentrically within the coupling and the outer hose to define a continuation of the outer passage, the clip comprising a generally cylindrical member having substantially concentric inner and outer surfaces respectively engaging the fitting and the coupling and having at least one opening between the surfaces thereof in communication with the outer passage on opposite sides of the clip for fluid flow therethrough.

In a method of making a hose assembly having fluid passages therein for respectively conveying a volatile liquid in one direction to a container and returning vapors of said volatile liquid from said container, said assembly comprising a flexible inner hose having an outer peripheral surface and defining an inner one of said passages, a flexible outer hose having an inner 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 an outer one of said passages, a coupling fixed to one end portion of said outer hose, a tubular fitting fixed to an end portion of said inner hose, and clip means holding said fitting and said end portion of said inner hose substantially concentrically within said coupling and said outer hose to define a continuation of said outer passage, the improvement comprising the steps of forming said clip means to comprise a generally cylindrical one-piece C-shaped member that extends in a circular arc that is greater than 180°and having substantially concentric inner and outer surfaces respectively engaging said fitting and said coupling, and forming said C-shaped member to have opposite ends spaced from each other to define an opening means between said surfaces in communication with said outer passage on opposite sides of said clip means for fluid flow therethrough.
