ABSTRACT A slide fastener comprises a pair of coiled coupling rows of synthetic-resin monofilament with each coupling element having a coupling loop or eye formed with a coupling head, a pair of monofilament segments extending away from the head, and connecting shanks joining adjacent coupling elements together. The shanks are received in pockets formed by longitudinal threads which pass alternately over and under the shanks so that the longitudinal threads and the shanks form a tape-like unit or support structure. Preferably the longitudinal threads constitute a warp with the shanks acting as a weft for the tape-like unit. The coupling ele- ments have a generally elliptical or flattened cross section where- by the coupling eye has its axis generally parallel to the major axis of the cross section of the monofilament.
