My invention relates to devices for securing
objects to walls and similar structures. While

understood that the device may be employed for
securing other objects which might be pipes for
carrying things other than electrical wires. An
object of the invention is to provide a device
of this character consisting of a plug of malleable
material such as pig lead adapted to be expanded

to that already described by providing a hole in

the plug in this hole.
The operation and advantages of my invention
will be fully understood in connection with the
foregoing description and the accompanying
15 drawing. The principle involved is substantially
the same in all of the forms disclosed, this prin
ciple embodying the idea of providing a plug of
malleable material upon which a ?exible element
is looped or otherwise secured, the device thus
20 produced being installed by expanding the plug
in a hole provided in a wall or other supporting
ible element having a portion thereof molded in
said plug and a portion extending therefrom
adapted to be bent around an object to be sup
ported from the Wall.
3. In a device of the character described, the
combination of a plug of molded malleable ma
terial adapted to be expanded in a hole provided
therefor in a wall or similar structure, and a ?ex
ible looped element having its loop molded in
said plug to provide two branches extending there
from adapted to be bent around an object to be 10
supported from the wall.
4. In, a device of the character described, the
combination of a plug of malleable material
adapted to be expanded in a hole provided there
for in a wall or similar structure, a strip of ?exible
branches extending therefrom, and an enlarge
ment containing a slot formed in the outer end of
one of said branches, the other one of said
branches being adapted to be bent around an ob 20
ject to be supported from the wall and the outer
end of said second branch being adapted to be in
structure. This device has been found to be very
efficient in practice. The expansion of the mal
leable material in the hole provided therefor gives
