Abstract
Abstract An anti-rattle element for a curtain of a closure, the curtain having a corrugated surface and, adjacent to its edges, either a strap riveted to crests of each corrugation or bridges extending across the troughs of the corrugations. The strap or bridges form detent surfaces engageable by a resilient latching tongue protruding rearwardly from a body of the anti-rattle element. The tongue has a tip that engages either the bridge or the strap to hold the anti-rattle element to the curtain. The body of the element also has first and second abutment side faces and a rear face having a recess therein which embraces a portion of an edge margin of the curtain. The anti-rattle element is connected to the curtain in such manner that its abutment faces are disposed respectively on opposite sides of the curtain and face outwardly therefrom.
