In the accompanying drawings, there is shown for the

tion may assume in practice.
In these drawings:
FIG. 1 is a fragmentary plan View of a slide fastener
and through which extends a hook-like lug 22 which co

the outward movement of the locking member. To either
side of this hook-like lug 22, there is arranged prefer

There is provided a pull member 25 having a trans
versely extending trunnion portion 26 at one end thereof
which is disposed in under the arcuated portion 15 of
the locking member 14 and between the same and the
outer surface of the Wing 5 for actuating the locking
member and the slider in an obvious manner.
It will be noted that both of the hook-like lugs 9 and

22 are substantially of the same height and that the
former extends at least to the outer side of the arcuated
portion 15 of the locking member 14 so as to protect the
same against any crushing effect to which the slider
might be subjected when in use.
It will be seen that the hook-like lug portion '9 not only
securely holds the locking member 14 in position on the
slider wing but protects the locking member from any
forces which might tend to distort the same, especially
when the slider is subjected to a pressing operation. The
opposite end of the locking member is free to move when
the pull member 25 is manipulated, as shown in the broken
lines of FIG. 4, but is limited in its outward movement by
?rmly grip the same whereby that end of the locking mem
ber is securely positioned on said wing, a locking projec
tion arranged on the opposite free end of said locking
member which projects normally through an opening in
said wing into said slider channel, and a pull member
having a transversely extending trunnion portion on one
end thereof which is disposed between the arcuated por
tion of said locking member and the adjacent wing por
tion forwardly of said lug portion.
