Bundling fastener for bars and wires

A bundling device, adapted to be secured to a preapertured support such as a panel or the like from one side thereof and to adjustable retain a plurality of elongated articles such as wires or bars comprising a bundling member of a predetermined length adapted to encircle and retain said articles in a bundle having at least one aperture therein and a fastener member adapted to be releasably attached to said bundling member and to securely fasten said bundling member to said preapertured support, said bundling member including a strip with oppositely undulating portions whereby when the opposite ends of said strip are superimposed and pressed together the undulating portions register and are secured together, said fastener including a head portion with a length dimension greater than the width dimension of said strip and a resilient engaging member adapted to extend through said at least one aperture and the aperture in said preapertured support to secure said bundling member relative to said support, said head portion having a plurality of resilient wings extending angularly therefrom adapted to engage the marginal edges of said strip and retain the fastener relative thereto, said resilient engaging member including a shank portion extending from the same side of said head portion as said resilient wings and a pair of resilient members integrally formed with said shank portion extending from the distal end of said shank towards said head portion adapted to engage the backside of said preapertured support, wherein said plurality of resilient wings are further adapted to bias the head portion away from said preapertured support to thereby maintain said pair of resilient members in engagement with the backside of the preapertured support, whereby said bundling device may be secured positively to supports of varying thicknesses.
