## Abstract

A cargo carrier tie-down assembly that utilizes a fastener made up of a shackle element that includes a wall in a form that is closed in two dimensions, defining an opening and wherein the wall also defines a pair of opposed apertures, a pin that can be inserted through the two apertures and a knob fastener element, having a head, that is sized to be passed through the opening when the pin is withdrawn from the wall, and that is retained when the pin is inserted into the two apertures. A tension member has one of the fastener elements attached to at least one end. The other fastener element is attached to the cargo carrier.
