PURPOSE: To simplify the assembly of a slider in which a new compression type latch part has been incorporated in the slider of a plastic zipper. CONSTITUTION: A slider 10 of a single-piece collapsible plastic zipper is that which is in the state that it bestrides a reclosable plastic fastener having a certain external form. The slider of the plastic zipper also has wing bodies 21, 22 that have been joined by a hinge so as to be retained by a non-reopenable latch tongue piece, because it is downwardly bent and deflected so as to be snappedly held, and is acted in the direction it is strongly engaged with by the force caused thereafter. |
