摘要： The present invention is a fastener system and method of using a fastener for removably securing bar grilles in window and door frames. A fastener having a tip or point at one end is inserted between a glass and a frame. The fastener has a pair of fins extending substantially perpendicularly from one surface and away from the glass. When appropriate mechanical forces are applied, the fins are bendable toward each other and have a tendency to return to their approximate original position after the forces are released. A slot is provided in the surface of a bar grille which comes into contact with the glass. The bar grille is snapped on the fastener so that the fins are forced toward each other as they enter the slot and are hooked into position as the fins return to their approximate original position. The bar grille may be removed by pulling on the grille so that fins disengage from the slot. When the bar grille is removed from the window, the fastener remains between the glass and the frame thereby preventing inadvertent loss.
