to be bent to one side to allow the tongue mem

returned'to its original position to bind the tongue s
between its edge and the adjacent edge of the ' ‘_
wall.v Throughout thisspec'iñcation and in the

In Fig. l, I represents the outer wall in juxta
posed relation to the inner wall 2. The outer
wall is provided with an opening deñned by the
wall edges 3, 4 and 5 and the appendant tongue
member 6. This opening substantiallyl overlies
the gate portion -I. In Fig. 2 is shown the outer
wall I and the tongue member 6, surrounded by
the wall edges 3, 4 and 5. 8 represents a scored
line adjacent the juncture ofi the tongue 6 and
the wall I. In Fig. 3 is shown the inner wall 2
edges meeting on a median vertical line II (Fig.
14). Fig. 15 indicates the, manner of registration
with the gate member 'I having a scored line 9 at
its juncture with the wall 2. _ Adjacent the scored
line and substantially at right angles thereto is
the wall edge- I0 terminating in the wall edge II
and completing the contour of `the opening in
which the gate lies is the wall edge I2.

view of such a device,- Fig. 17. Similar conditions '
prevail with the embodiment shown in Figs. 9
to 11 inclusive insofar as the widened tongue 20
member is concerned, except that no impediment
to the entrance of the tongue member exists on
one side due to the fact that the side II of the
opening in the inner wall 2 is formed at an angle
which allows the tongue member to pass unob 25

device will be registered in the manner indicated
herein while for separate pieces a similar regis
tration is made between the parts prior to the
fastening operation.
It will be noted that the operation of fastening
is very simple. The tongue member is merely
pushed sidewise (facewise) through the open
ing in the opposed wall, displacing the gate
member which through its own resiliency has a 45
tendencyto return to its original position after
the tongue member is bent far enough inward to
clear it. The .gate member is forced into the
opening to its original position where it securely
locks the tongue member in place against either 50
