An elongate supply ribbon of plastic material for supporting bolt-like fastener elements is structured with a back wall portion and a plurality of tongues extending from opposite sides of the back wall portion generally perpendicularly to the plane thereof. Bending regions interposed between the back wall portion and the tongues are formed with notches which have sides abutting each other when the tongues are bent to extend perpendicularly from the plane of the back wall portion in order to provide bearing support for the tongues.
