fastening to complete the installation of the clip.
It is now apparent that the hook 26 and
rounded end part 21' serves as snap fasteners
which may be interengaged or hooked together
by pressing the end portion 2'! inwardly to snap
the part 21’ into the hook 26. This arrange
ment facilitates sub-assembly operations in which

Another form of my invention shown in Fig. 6
in Figs. 2 and 3.
If desired the end portions 8 and 9 may be
forced onto the fastening after the latter is in
serted through the support following which the
fastening is tightened as aforesaid. The end por
tion 8' may be pushed inwardly while the end
portion 9 is disposed against the support, to move
the tongue out of position to engage the fasten
ing which may then be inserted from the outside,
?rst, past the tongue then through the openings
III and the support and ?nally turned to force
the tongue into locking engagement therewith
and draw the ends of the loop together. How
ever, it is possible to insert the fastening in this
manner without ?exing the tongue out of the way
as next above noted, inasmuch as the resiliency
of the tongue and end portion 8' make it possible to force the fastening past the tongue and
consists in providing an end portion 30 of any
of the clips here shown, with a locking tongue
3| corresponding to the tongue I5 but provided
with a recess or cut-out 32 in the rounded por
tion 33 to reduce the spring tension of the tongue.
In some instances a clip having a more ?exible
locking tongue like the one shown in Fig. 6 may
be preferable.
It should be noted that the ends 8 and 9, the
tongues I5 and the openings III are so formed
and relatively arranged that the lower marginal
portion of the opening I!) in the end 8 and the
upper marginal portion of opening II] in end 9
are forced into tensioned and threaded contact
with opposite sides of the fastening II as shown
in Fig. 3, when the fastening is tightened and
draws the tongue I5 into tensioned and threaded
contact therewith, thereby effectively locking and
through the openings I0 and the support, after 30 holding the clip on the fastening as though a
which the fastening is turned to tighten it and
lock nut were used.
secure the clip in place as aforesaid.
With reference to Fig. 3, it is seen that the
tongue I6 is drawn into tighter contact with the
fastening II as the latter is tightened yet the
tongue can be readily lifted or moved out of look
ing contact with the fastening by ?exing the end
8’ inwardly.
The modi?ed form of clip shown in Fig. 4 dif 40
fers only in that the loop I8 is of true circular
form and the ends I9 and 20 are considerably off
set, there being relatively long lateral extension
portions 2| beyond the circular loop proper, on
which extensions the ends I9 and 20 are formed.
End I9 has a locking tongue 22 identical with
the tongue I5 shown in Figs. 1, 2 and 3 and which
operates in the same manner relative to the fas
tening 23. A cushion 24 is provided on the loop
H in the same manner as in Figs. 1, 2 and 3. This
circular cushioned loop formation rather than
the somewhat oval formation of the loop shown
in Fig. 2 may in some instances and installations
be more desirable and better adapted to support
ing certain conduit or other lines.
Another modified form of my invention as
shown in Fig. 5 differs from the form shown in
Fig. 2 only in that the inner end portion 25 which
corresponds to end portion 9 is provided with a
turned out end forming a hook 26 adapted to hook
over the end portion 21 which latter corresponds
to the end portion 8 and has a rounded outer end
21’ over which said hook extends to reinforce its
bent part and to hold the clip pre-assembled on
a conduit or bunch of wires with the ends ready
for reception of the fastening 28 when installing
the clip. In this form the end portion 21 is
straight out to the rounded part 21'. A locking
lip or tongue 29 is formed on the end portion 21
in the same manner as the tongue I5 and coop
erates with the fastening 28 in the same manner
to lock the clip in place. This tongue normally
appears as shown in dotted lines in Fig. 5 and will
be drawn inwardly into locking position as shown
in full lines in Fig. 5 upon manipulation of the 75
While I have shown and described speci?c em
‘sediments of my invention I do not limit myself
to the exact details of construction set forth, and
the invention embraces such changes, modifica
tions and equivalents of the parts and their
formation and arrangement as come within the
purview of the appended claims,
I claim:
1. In a clip for supporting wires or a conduit, a
spring metal strap formed into an open loop hav
ing normally spaced apart apertured end portions
providing attaching ears adapted to be brought
together to close the loop and to align the aper~
tures therein for reception of a fastening for
securing the clip to a support, and a spring look
ing tongue on one of said end portions, said
tongue having its outer end edge disposed to have
tensioned end contact with the fastening to hold
the clip thereon and being movable out of lock
ing contact with the fastening responsive to the
?exing of said one end portion toward the other
end portion.
2. In a clip for supporting wires or a conduit, a
spring metal strap formed into an open loop hav~
ing normally spaced apart apertured end portions
providing attaching ears adapted to be brought
together to close the loop and to align the aper
tures therein for reception of a fastening for
securing the clip to a support, one of said end por
tions being bent angularly outward at a point
beyond the aperture therein and then ‘bent over to
provide a spring locking tongue extending back
toward the loop in outwardly spaced relation to
the associated end portion, with its outer end edge
disposed to have tensioned locking engagement
with the threads of a threaded fastening extended
through the apertures in said end portions for
securing the clip to a support, said tongue being
arranged to be ?exed inwardly toward its asso
ciated end portion for forcing said end portions
together upon the tightening of said fastening
to close the clip and secure it to the support.
3. In a clip for supporting wires or a conduit, 8.
