Clampless hose retainer mechanism

A rubber hose (20) of an air supply assembly (10) is secured to a resonator (14) by an inserted internal tube (18). A tapered insertion end (44) of the internal tube (18) is inserted into the rubber hose (20) and slides along an angled surface of the rubber hose. The tapered insertion end (44) presses the rubber hose (20) against a hose neck of the resonator (14) to retain and seal the rubber hose. A retention end (42) of the internal tube (18) secures the tube to the resonator. The retention end (42) includes a recessed portion (50) positioned between a pair of flanges (52,54). The tube neck of the resonator engages the recessed portion (50), the flanges (52,54) securing the internal tube (18) in place.
