Abstract
Abstract This fastening device comprises a central internal plug formed with retaining notches and engageable in an external peg consisting of separate legs formed with internal and external notches and connected to the inner end of said plug by means of flexible strips molded integrally with said legs and said plug. The legs are folded against the plug and the latter comprises a flange for limiting its inward movement and means for supporting the object to be fastened. The assembly is molded as a one-piece member in a three-section mold with one joint plane formed with the impression for molding said legs in a plane perpendicular to the axis of said plug, said plug being molded in the other mold sections.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
224 words
A device for fastening an object to a support comprising an expansible peg adapted to be driven into a hole of the support; an expansion plug located centrally in said expansible peg and having a front end and a rear end, said expansion plug having a polygonal cross section and said expansible peg comprising a plurality of legs disposed about said expansion plug, the number of said legs corresponding to that of the faces of said plug; flexible connecting strips connecting the front end of each leg to the front end of said plug, said connecting strips are folded on themselves in such a manner that the rear ends of said legs are spaced from the rear end of said plug; and a flange provided on said plug adjacent the rear end thereof for limiting driving of said plug into the peg-forming portion of the device, said legs, said strips and at least a portion of said plug being integrally molded from plastic material and the lengths of said strips being such that they permit by the distortion thereof forward movement of said plug relative to said legs during driving of the device into the hole, the external faces of said legs having a substantially convex shape so that the device has a circular cross section when said legs are folded against said plug.
Claim 2
Independent Claim
224 words
A device for fastening an object to a support comprising an expansible peg adapted to be driven into a hole of the support; an expansion plug located centrally in said expansible peg and having a front end and a rear end, said expansion plug having a polygonal cross section and said expansible peg comprising a plurality of legs disposed about said expansion plug, the number of said legs corresponding to that of the faces of said plug; flexible connecting strips connecting the front end of each leg to the front end of said plug, said connecting strips are folded on themselves in such a manner that the rear ends of said legs are spaced from the rear end of said plug; and a flange provided on said plug adjacent the rear end thereof for limiting driving of said plug into the peg-forming portion of the device, said legs, said strips and at least a portion of said plug being integrally molded from plastic material and the lengths of said strips being such that they permit by the distortion thereof forward movement of said plug relative to said legs during driving of the device into the hole, the external faces of said legs having a substantially convex shape so that the device has a circular cross section when said legs are folded against said plug.
