摘要： A profile element for connecting a vehicle pane to a water draining chamber includes a first segment affixable to the vehicle pane. A second segment has, at an upper portion, a bearing rib having at least one seal configured to be disposed at a lower edge of the vehicle pane and, at a lower portion, a snap-in recess configured to receive rib of the water draining chamber through an engagement aperture which is delimited in the insertion direction by a lower-most surface of the bearing rib and an upper-most surface of the resilient leg. A detent element is disposed in the snap-in recess so as to facilitate inserting the rib of the water draining chamber in an insertion direction into the snap-in recess and present a larger resistance to extracting the rib from the snap-in recess in an extraction direction opposite the insertion direction.
