ABSTRACT An apparatus and method for connecting pipe ends. In one embodiment sleeves having serrated inner surfaces are force fit onto the ends of pipe sections. The sleeves are positioned within a tubular connector having oppositely wound helical grooves, with helical grooves in the sleeves adjacent thereto. Wire is fed through a slot in the connector into the chambers formed by the adjacent grooves. The connector is rotated causing the wire to be drawn into the chambers to create a screw and thread effect thus causing the sleeves to be drawn inwardly until frusto-conical surfaces thereon mate to form a firm connection.
