An emergency opening slider to be mounted, in addition to the usual fastener slider, in any selected position on interlocked rows of fastener elements to permit the fastener to be forced open from the selected position in an emergency. The slider body has a guide channel therethrough which consists of contracted terminal portions at both ends and an expanded midportion, with the latter portion divided into a pair of branch channels where the rows of fastener elements are incapable of interlocking engagement. The slider body includes a portion or portions which, upon application of operating force as through a pull string connected thereto, are displaceable to permit disengagement of the fastener elements. |
