In one form of the construction employed, the tapes or
ribbons 17, 17' are disposed upon both side surfaces of
the scoops, as clearly noted in FIG. 2 of the drawing;
whereas, in FIG. 3, the tapes or ribbons 17, 17’ are io
cated only on outer surfaces of the scoops and, with this

In FIG. 3 of the drawing, the Stringer tapes are des
eratively engaging the Stringer scoops, in coupling and
ignated by the reference characters 21, 21'. In FIG. l
of the drawing, I have shown the contracted end portion
uncoupling the same, will have direct bearing upon edge
of a slider 22, this end portion being shown in section in
portions of the scoops.
More particularly, the invention deals with separable 15 FIG. 2 of the drawing, the dared background showing of

The novel features of the invention will be best under- '
It will appear, from a consideration of FIGS. 2 and 3,
that the tapes or ribbons 17, 17’ are disposed within end
boundaries of each of the scoops and within end bound
