ABSTRACT OF THE DISCLOSURE A vacuum cleaner hose assembly and method of making same are provided herein. The assembly comprises an elongated vacuum hose having a hose end, a plurality of electrical conductors extending along the vacuum hose with each conductor having an end portion disposed immediately adjacent the hose end, a plurality of electrical connectors each fixed to an associ- ated end portion of an associated conductor, a flexible hose fitting fixed to the hose end with the fitting having a plurality of the electrical connec- tors embedded therein which are movable with flexing movements of the fitting, a rigid hose adapter operatively connected to the fitting, an electrical device carried by the adapter and connected to the embedded connectors with the device having precisely aligned integral electrical connectors, and cooperating portions on the adapter and electrical device self positioning the electrical device relative to the adapter with the precisely aligned electrical connectors readily accessible for easy mating with cooperating electrical connectors. The positioning means comprise a positioning sur- face on the support structure and coopending surface on the adapter. These surfaces are self-aligning surfaces which self-align upon connecting the adapter and the electrical device to the fitting and the embedded connec- tors. By these means the possibility of damage to the electrical connectors as well as to the fitting and/or associated component requiring scraping of samaged parts and resulting in unnecessary excessive costs is practically obviated.
