A fluid-tight slide fastener stringer comprising a support tape made of a fluid-tight soft material, and a row of discrete coupling elements mounted on the tape along an inner longitudinal edge portion thereof. Such tape margin is folded so as to provide therealong a contact portion engageable with a corresponding contact portion of a like companion stringer to effect a fluid-tightness between the two stringers. In order to absorb or reduce undue stress exerted on the individual coupling elements, each coupling element has a slot extending parallel to the general plane of the stringer transversely through the whole width of a coupling head portion and also extending longitudinally of the same coupling element through the coupling head portion into a base portion. |
