Changes may be made in the form, construc

The outer end of the member 25 is adapted to
be held in locked position by a keeper 32. This
Ikeeper 32 may comprise a groove 33 formed on
the upper outside edge of the member I6 sub
stantially midway between the free ends thereof.
Instead of providing a groove 33, Fig. 3, an out
standing pin 34 may be employed so as to hold
the member 25 in proper position, Figs. ‘land-5.
In actual use, the guard I0 and its cooperating
clamping member 23 is in the position shown in
Figs. 1 and 2, with the member 24 in its upper
most position lying against the upper guard
wires I I. When it is desired to unlock the guard
ID, the member 24 is moved downwardly to the
respective positions shown in Figs. 3, 4 and 5.
As the clamping member 24 is moved downwardly
to the position shown in Fig. 3, the parts will be
in unlocked position, except the member 25 will
still be locked Or received in its keeper 32—34.
Continued downward movement of the member
24 will release the member 25 from the keeper
32, as shown in Fig. 4, at which time the mem
ber 24 is free to be moved downwardly, as shown
in Fig. 5, whereby the clamp 23 is completely

hereby reserved to make all such changes as
fairly fall within the scope of the following
claims.

adapted to clamp onto a handle guard or cable
and comprising a ?rst single piece of wire hav

and extending outwardly from said collar part
but surrounding the said collar part in the form
of a loop, loops formed in said wire near the
pivoted ends thereof to provide eyes, and a second
"single piece of wire having its ends pivotally
20 mounted in said eyes and adapted to extend
around the second collar part and away from
.said ?rst wire, said second collar part providing
a keeper for said second wire, said ?rst wire upon
movement about its pivotal connection with said
?rst collar part providing a lever for moving the
second wire toward or away from the second col
