  • each of said electrical connectors has a U-shaped portion 10 defined by a bight and a pair of outwardly extending legs and said knife-like portions of each connector comprise the outwardly extending legs thereof.
  • each of said slots in each knifelike portion is a keyhole shaped slot.
  • a method of making a vacuum cleaner hose assembly comprising the steps of providing an elongated vacuum hose having opposite ends and a central longitudinal axis, extending a plurality of electrical conductors in a helical pattern along said vacuum hose so that each conductor has opposite end portions each disposed in a helical path about said longitudinal axis and each said opposite end portion being arranged immediately adjacent the opposite ends of said vacuum hose, providing electrical connectors at opposite end portions of each conductor, each of said electrical connectors comprising a knife-like portion provided with opposed edges defining sides of a slot, arranging each knife-like portion generally transverse the helical path of the associated end portion of its conductor, relatively moving the conductor end portion and associated electrical connector together to wedge said conductor end portion between said opposed edges to provide a firm mechanical and electrical connection wherein each electrical connector is disposed substantially parallel to said longitudinal axis, and forming a pair of hose connectors around said opposite ends of said vacuum hose as an integral part thereof to thereby simultaneously embed associated ones of said electrical connector
  • step of extending a pair of electrical conductors comprises the step of extending a pair of electrical conductor wires having comparatively high strength in said helical pattern along the length of said vacuum hose whereby said electrical conductor wires also serve as reinforcing wires preventing collapse of said vacuum hose.
  • a method as set forth in claim 12 in which said step of providing a vacuum hose comprises providing a vacuum hose made of a thermoplastic material and said step of forming a pair of hose connectors around said opposite ends of said vacuum hose comprises forming said hose connectors of a thermoplastic material which is compatible with the thermoplastic material of the vacuum hose and by injection molding process.
  • a method as set forth in claim 12 in which said step of relatively moving the conductor end portion and associated electrical connector together comprises moving each electrical connector radially outwardly against its conductor end portion with a hammer member and against a backup member.
