Retaining device for concealed slide fastener

摘要

A retaining device for retaining a terminal end portion of a so-called concealed slide fastener in closed disposition against accidental splitting or disengagement of the intermeshed fastener elements at the end portion. The retaining device has a base; a pair of opposed inwardly directed longitudinal flanges having vertical side walls and horizontal upper walls having their longitudinal edges disposed in spaced, confronting relationship; and a pair of symmetrical projections at one end of the device each extending integrally with the respective horizontal walls beyond the end of each of the side walls. The pair of opposed inwardly directed longitudinal flanges define with the base a channel functionally analogous to that of a slider.
