Q'lhe lower ends of the legs 21 and22 are pointed to provide prongs 249 for biting into thematerial of no the support. B; thesepronirs 24 being flattened as "at 25 in converging; relation toward the pointed ends there'ofi.

.In the assemblage of the staple element 20 to the strap m'ember'lO whichis effected in the manufacture of the retaining devices A. the legs 21 and 2-2 are inserted through the apertures Win the strapflanges 15 and 16 so that the arcuat bite or head portion 23 of the staple 20 overlies in abutting engagement with the outer surface. of the bight or head portion 14. of strap 10. as is illustrated in Figures 1', 2; and-3 of the drawing. In this arrangement. the upper portions of the staple legs 21 and 22am in 'ahutting engagement with the outer surfaces of the strap legs 12' and 13. and the main portion 'of said legs 21 and 22 extend below the lane in which the strap flanges 15 and 16 ie. As is illustrated in Figure 4, the connection of a leg of the staple 20 in the opening 17 of the strap flange is an arrangement However, in the assemblageof whereby the staple leg might become detached with respect to the strap flange.

t e staple and strap menitiers, the staple legs 21 and 22 are provided on opposite sides with the.

upper c imps 25 and 26 upon diametrically opposed sides thereof, by means of any approved crimping tool to provide projections 27 and 28 respectively, overlying the top surfaces of the flanges 15 and .16. In order.

to permanently and securely attach the stra member 10 to the staple 20, the lower crimpu 29 and 30 are provided in the legs 21 and 22 of the staple member 20 at diametrically opposed points in order to respectively provide the projections 31 and 32 which engage. the under surface of the strap flanges 15' and 16. The crimps are arranged in the staplelegs so that each leg has'fou'r projections or lugs therein, two upper lugs,.and

two lower lugs, to securely and permanently attach the flange through which said: leg is disposed.

From-the foregoingdescription ofdthis invention, it can be seen that a compact and simple retaining device has been rovided,

which is particularly well adapte for use in connection with-the supporting and mounting of armored cables;- fGreenfield metal flexible: conduits; pipes; wires; moulding and other devices. Heretofore stapleshave been employed, which injure flexible cables and do not providean effective retaining arrangement due to the limited surface of pipe or conduit which the same may engage. Also straps individuallyhave been employed, but which take con'siderable'ti'me for the attachment of the same, in viewiot; the fact that a plurality of retaining nails" or staples have to be employed therewith, which are of course detachable with'iespect to the -stra devices, so that considerable time is emp oyed in securing the same to a support.
