Abstract: Fasteners for securing a shaped embellishing molding across the gap between the peripheral edge of a fixed window panel and fillister support surface in which the panel is mounted in an automotive vehicle. The fasteners are integrally fabricated from a material such as plastic and are adapted to mount in the gap without the need for welded studs or other means secured to the fillister. Each fastener includes a base and pair of projecting resilient wings which are downwardly flexed to fit in the gap. The wings include beveled bearing faces that resiliently bear against the inside corner of the mounted panel and develop a reacting force tending to load and position the fastener flushly against both sides of the fillister. The beveled bearing faces also allow the fastener to take up large tolerances both in the width of the gap and in the spacing of the panel from the inner side of the fillister.
