A slide fastener stringer having a continuous zigzag-shaped thermoplastic molded coupling element strip. The strip includes a succession of spaced coupling elements, each having a pair of first and second legs extending from a head in a common direction, and a plurality of first and second solid connecting portions alternately disposed at opposite sides of the strip and extending one between each adjacent pair of the coupling elements. Each first connecting portion and each second connecting portion extend between an adjacent pair of the first legs and between an adjacent pair of the second legs, respectively. The connecting portions are thin or more slender than the legs. A pair of connector threads extends transversely of the coupling elements through the full length of the strip and they are embedded in the first and second legs, respectively, of each coupling element, each connector thread being disposed close to and extending along a respective one of such two series of the first and second connecting portions. |
