This invention relates to sliders for use on
ings, the yoke will preferably be composed of
separable fastener stringers to couple and un
couple the stringers. More particularly, the in
vention relates to devices of this kind wherein the
slider body is composed of separate die cast parts
coupled together and reinforced by a coupling
yoke preferably of a material stronger than the
material employed in the cast body portions of
the sliders. Means is also provided for keying
the yoke to the body parts of the slider,’ as well as 10
steel or other materials stronger than the metals
employed in the casting. On the other hand,
when the slider body is composed of plastic mate
rials, either molded or die cast, the reinforcing
or coupling yoke can be composed of any type
and kind of material, for example, ?ber or metal,
or of a die cast metal.

the‘ degree of improper functioning of the slider

It will be understood that by constructing the
