ABSTRACT:
A handle assembly for securing a vacuum hose to an intake nozzle of a vacuum cleaner system. A handle housing having first and second mating handle housing sections and a plurality of oppositely facing ridges and oppositely facing grooved portions protruding from inner surfaces of the housing sections is adapted to house a ribbed end portion of a vacuum hose and an elbow section having a shoulder portion protruding therefrom. The ridges and grooved portions are adapted to abuttingly engage the ribbed end portion of the vacuum hose and the shoulder portion of the elbow section respectively when the first and second handle housing sections are matingly engaged, to thereby prevent clockwise or counter-clockwise rotation of the vacuum hose as the handle assembly is articulated into various positions during use. The vacuum hose further includes a relatively smooth inner surface which is operable to slide over a portion of the elbow section housed within the handle assembly housing. The elbow operates to grip onto the vacuum hose to further help secure it to the housing. The vacuum hose is thus secured to the handle housing without the need for screws, adhesives or specially formed fittings secured to the end of the vacuum hose.
