ABSTRACT:
A lockable slide fastener slider having a guide groove which allows a pair of rows of coupling elements to pass smoothly through a guide channel without entering an aperture communicating with the guide channel, even when the coupling elements are displaced toward the aperture. The guide groove is defined jointly by a bottom wall and a pair of oblique sidewalls diverging toward the guide channel, the bottom wall having a width substantially the same as that of the aperture. The peripheral wall bounding the aperture has an oblique end portion facing the guide channel and merging into the oblique sidewalls.
