A coupling member assembly for a flexible hose, the flexible hose automatically expands longitudinally and laterally upon the application of a fluid pressure. Upon release of the fluid pressure within the hose, the hose will automatically contract to a contracted condition. The hose includes an inner tube made from an elastic material and an outer tube made from a non-elastic material that secured together by the coupling member. The inner tube is positioned concentrically within the outer tube in both a contracted condition and an expanded condition. The outer tube is secured to the inner tube only at a first end of the inner and outer tubes by use of a male coupler member and at a second end of the inner and outer tubes by use of a female coupler member. The outer tube moves laterally and longitudinally with respect to the inner tube when the tubes are transitioning between a contracted condition and an expanded condition.
