A molded component to connect a motor vehicle window with a water box includes a first segment affixable to the vehicle window and a second segment having a detent cavity bounded by a resilient leg and configured to receive a rib of the water box in an insertion direction so as to detachably affix the water box in a frictionally and/or geometrically interlocking manner in the detent cavity. A detent element projects into the detent cavity at an acute angle relative to the insertion direction such that the resilient leg is elastically deformed to a greater extent during an extraction of the rib of the water box from the detent cavity than during an insertion of the rib of the water box into the detent cavity. This facilitates the insertion and presents a greater resistance to the extraction of the rib from the detent cavity.
