ABSTRACT:
Stringers of a slide fastener are attached to the connecting edges of a sheet for opening and closing thereof and a tightening device is disposed in an intermediate portion of the sheet along the lengthwise direction of the fastener stringers so that the tightening device can tighten and relax the sheet in a direction intersecting said connecting edges at right angles. When the fastener is zipped to open or close the sheet, the tightening device is to be operated beforehand to loosen the sheet. By the provision of this tightening device, the operation of the fastener can be freely functioned as a zipper, and flapping of the sheet can be prevented by the sheet-tightening action of the tightening device.
