Releasable securement device

Abstract

A releasable securement device for use with material including a stay portion having a projection surface; and projections that extend from the projection surface at an acute angle, the projections being substantially parallel, pointing in substantially one planar direction, and having a predetermined flexibility. The acute angle and the predetermined flexibility are selected to allow the material to slide past the projections when the material engaged with the projections is pulled in the one planar direction, and are selected to prevent the material from sliding past the projections when the material is pulled opposite the one planar direction, the projections bending and allowing the material to slide past the projections when the material engaged with the projections is pulled opposite the one planar direction and force on the projections exceeds a predetermined force.
