Slider for concealed slide fastener

Abstract

A concealed slide fastener slider comprises: a slider body having a guide post on which an attachment lug stands; a resilient locking lever attached at one end to the attachment lug and having at the other end a locking pawl retractably inserted into an element guide channel of the slider body; a clamp having an aperture and a central bent portion bent in an inverted L shape so that the clamp can fall flat to a rear side of the slider body; and a pull tab loosely threaded through the aperture. When a cloth is jammed between the slider body and the clamp, only a front part of the clamp assumes an upright posture but a rear part of the clamp to which the pull tab is attached assumes a horizontal posture, thus causing the pull tab to rest on the cloth.
