A slide-fastener stringer having a pair of coupling elements mounted, for intermeshing upon movement of a slider therealong, upon juxtaposed edges of respective support tapes. The support tapes are each provided with a longitudinal row of openings for cooperation with the needle mechanism of an apparatus designed to attach the stringer to a garment or other fabric. The openings are formed by pushing back at least one warp thread extending parallel to the coupling element by thrusting a wedge-shaped needle or lance into the weave. A plurality of such lances may be provided in transversely staggered longitudinally spaced relation to force back the warp thread in successive stages.
