ABSTRACT:
A device for holding a slider in position during threading onto a slide fastener chain includes a housing having a support surface for supporting thereon a slider body upside down, and a slit receptive of a pull tab hanging from the slider body. A lever has a pair of juxtaposed first and second arms disposed one on each side of the slit, there being on the first arm a locking projection movable into and out of the slit. The lever is pivotable in the housing between a slider-holding position and a slider-release position. The second arm extends beyond the first arm to such an extent that as the slider is placed on the support surface, the second arm is pressed downwardly by a yoke of the slider to cause the lever to be pivotally moved to the slider-holding position. When a reverse or upward pull is exerted on the slider during the threading of the fastener chain through the slider, the second arm is brought into contact with the slider body, thus preventing the lever from being pivotally moved to the slider-release position.
