Abstract

An anchor useful for attaching articles to a member of predetermined width including a support section, a pair of arms extending from the support section, each arm extending to an end away from the support section, a retainer at each of the ends of the arms being affixed so that as the arms are pushed onto a member of predetermined width, the retainers force the pair of arms apart and when the arms are pulled off the member of predetermined width, the retainers tend to grip the member of predetermined width, where the arms are spaced apart from one another by a distance substantially equal to the width of the member of predetermined width, where the retainers define a plane with which the retainers are substantially aligned, where the retainers extend toward each other and toward the support section such that when viewed from a line of sight perpendicular to the plane formed by the retainers, the angles formed by each of the retainers and each of the respective arms is substantially acute and the arms are substantially parallel, and where the contact point of the retainers with the member of predetermined width when the arms are pushed onto and around a member of predetermined widt…
