Retaining wires

A wire retaining system includes a wire clip and fastening receiver for releasable attachment of a wire clip on a supporting surface to retain a wire. The receiver includes an adhesive backing and touch fastener elements. The wire clip includes two wire receptacles with respective receptacle openings facing different directions and touch fastener elements for engagement with the touch fastener elements of the receiver. A first receptacle is oriented with the receptacle opening facing a desired direction and the wire extends across the receptacle. The releasable wire clip can be reoriented with the second receptacle facing a desired direction and a second wire extending across the second receptacle. The wire clip can be packaged preassembled on a light strand with the touch fastener elements of the wire clip and receiver engaged. A method of forming fastener products includes forming a rigid extrusion having fastener elements formed from extruded rail segments.
