Abstract
The hose assembly, preferably for use as a flexible hose for a vacuum cleaner or the like, includes a pair of side by side electrical conductors helically wound integrally within the hose. Each conductor is doubly insulated. A tubular coupling cuff is screwed onto one end of the hose for coupling the hose to other equipment. The cuff is molded with a recessed area on the inner diameter thereof. Wire connectors between conductors in the hose and wires in an electrical wiring harness are mounted in a strain relief molded onto the harness and mounted in the recess so that when the harness is pulled, the wires thereof will not become disconnected from the conductors of the current carrying hose.
