In leggings and other articles of apparel as well
as articles of merchandise which open from the
lower end of a vertical arrangement of the fas
tener, it is desirable to retain the slider against
upward movement on the stringers, or. in other50 words, to prevent the stringers from opening, es
pecially where the stringer lower ends are sub

of the drawing. When in this position, the linger

cidental displacement when in its locked posi 45
tion so as to prevent movement of the linger
piece or pull, especiallyl in normal uses of the
device, it being understood, however, that the

from its locked position and swung into the dotted 50
