A fluid-tight slide fastener of the type in which an inner longitudinal edge portion of each of opposed tapes is folded so as to extend around base portions of successive I-shaped coupling elements and in which successive U-shaped first clamping strips surround, in clinched form, the folded edge portion over the base portion of the respective coupling element, each of opposed top stops includes an elongate plate of an I-shaped cross section corresponding to the shape of the coupling elements and having a base part surrounded by the folded edge portion of the tape, and a second clamping strip of a C-shaped cross section corresponding to the shape of the first clamping strips and surrounding, in clinched form, the folded edge portion over the base part of the elongate plate. When the slide fastener is fully closed, the opposed top stops are entirely received in the guide channel of a slider. |
