Abstract

A resilient fastener for attaching an article such as a cable or pipe to a stud having a stem projecting outwardly from a support surface and a head on the end of the stem. The fastener comprises a base having an undersurface, two generally parallel side edges and two arms which extend upwardly from the base and which are adapted to engage and hold an article in co-operation with the base. In an alternative embodiment one arm overlies the base. Two flanges are spaced from the underface of the base and are joined to the parallel sides of the base by webs of material, the flanges having edge surfaces which define with the base a slot which is generally T-shaped in section and which is adapted to slidably receive the stud so as to mount the fastener thereon. Abutment means are provided in the slot to limit movement of the stud along the slot and a neck portion is provided in the slot to resist movement of the stem of the stud along the slot. The neck portion of the slot is defined by the facing edges of the flanges and is spaced from the abutment means by a distance such that the neck portion of the slot urges the stud against the abutment means. The resilience of the base is such that the facing edges of the flanges can be readily spread apart when the arms are free to move inwardly allowing the base to bow and the facing edges of the slot are held firmly against spreading when an article is engaged by the arms and bowing of the base is resisted thereby.

Claims

1. A resilient fastener for attaching an article to a stud having a stem and a head, the fastener comprising a base having an underface and two generally parallel sides, two arms extending upwardly from the base, the arms being adapted to engage and hold an article in co-operation with the base, two flanges spaced from the underface of the base and joined to the said parallel sides of the base by webs, the flanges having facing edge surfaces and defining with the base a slot which extends through the entire length of the fastener and is open at both ends and which is generally T-shaped in section and which is adapted to slidably receive the stud so as to mount the fastener thereon, abutment means depending from the underface of the base into the slot adapted to limit movement of the stud along the slot and a neck portion in the slot adapted to resist movement of the stem of the stud along the slot, the neck portion of the slot being defined by the said facing edges of the flanges and being spaced from the abutment means by a distance such that the neck portion urges the stud against the abutment means, wherein the resilience of the base is such that the said facing edges of the flanges can be readily spread apart when the base is free to bow and the said facing edges are held against spreading when an article is engaged by the arms thereby resisting bowing the base.

2. A fastener as claimed in claim 1, wherein the base is substantially flat and is adapted to bow when the flanges are spread apart.
