ABSTRACT:
A two-part fastening clip made of a hard-elastic plastic material for fastening a piece of molding to a panel. The device includes an upper part having a cover plate, with the molding being secured to one side of the cover plate, a stopper element that extends perpendicularly out from an opposite side of the cover plate in a direction away from the molding and a bulge on its free end that tapers conically in both its axial directions. The device also includes a lower part that can be anchored in a hole in the panel and has a socket casing having a through opening therein for receipt of the stopper element of the upper part and a constricted edge in the opening behind which the bulge of the stopper engages to lock the two parts together. A first flexible sealing diaphragm on the lower part seals against the panel when the lower part is anchored to the panel to seal off the hole in the panel and a second flexible sealing diaphragm extending in a direction opposite from the first diaphragm seals against the cover plate of the upper part when the stopper is inserted into the opening in the socket casing and the bulge on the stopper is engaged behind the constricted edge of the opening to seal off the opening in the casing.
