Abstract
A fluid-impervious slide fastener is disposed; an covering abutting member is formed in a central slit of a pair of support tapes, the covering abutting member has a first covering body having a covering layer and a second covering body having a covering layer; when the fluid-impervious slide fastener is in a coupled status, the first covering body and the second covering body are able to elastically abut against each other so as to form a tightening deformation, thus the central slit is provided with a fluid-impervious function against a fluid, for example a liquid, of capable of bearing a hydrostatic pressure of 30 gf/cm2.
