Abstract: The invention relates to a cover device for sealing assembly recesses on roof-drip moldings of motor vehicle bodies that run in the longitudinal direction of the vehicle. The device consists of a cover holder (9) that can be placed in the roof-drip molding (1) in the area of the recess and a cover (8), which is mounted in such a way that it can pivot crosswise to the longitudinal direction of the roof-drip molding, for sealing the recess (5). Said cover holder (9) also has a recess (16) in its floor part (10). Mountings (17) are molded on both sides at one end of the recess (16) and have bearing journals (18) that face each other and that engage in corresponding, lateral bearing holes (19) that are provided at one end of the cover (8), in such a way that they can expand elastically. A support (20) on which the cover (8) rests in its closed position is located at the other end of the recess (16).
