According to the invention, a wedging leg extends inwardly from one of the walls of a channel-shaped weatherstrip carrier and reaches angularly toward the base of the weatherstrip carrier. The wedging leg has a foot including a toe portion which frictionally engages with the flange so that the attempted removal of the carrier from the flange is resisted by the frictional engagement of the toe portion with the flange and the wedging leg is placed in a condition of axial compression tending to bow the wedging leg. The wedging leg has a relatively weakened knee joint generally at the mid-length thereof which defines and controls the bowing of the wedging leg as the carrier is removed from the flange. The foot of the wedging leg also has a heel portion which is carried into progressive frictional engagement with the flange during the progressive removal of the carrier from the flange to thereby increase the area of frictional contact between the flange and the foot so that the wedging leg progressively resist the removal of the carrier from the flange. The carrier also has a reaction arm which extends inwardly from the wall generally adjacent the knee joint of the wedging leg so that the reaction arm is engaged by the knee of the wedging leg upon bowing of the wedging leg thereby supporting the wedging leg at a point closer to the foot to minimize the bowing and thereby maintain the wedging leg in generally columnar axial compression and maintain the foot in substantial frictional engagement to resist removal of the carrier from the flange.
