ABSTRACT:
The invention relates to a single-pieced sealing cover (1) made of a thermoplastic elastomer, especially used to seal an opening (22,22′, 22″), comprising a base body (5) with an adjacent peripheral collar (7) which turns into at least one elastic sealing lip adjacent to one side of a carrier (10, 10′). The collar (7)comprises at least one detent ring (12) located opposite the at least one sealing lip (10, 10′).The invention is characterized in that the collar (7) is connected to the sealing lip (10, 10′) by means of an intermediate area (14) extending parallel to a covering surface (F) of the carrier (20, 20′, 20″), whereupon the detent ring (12) protrudes into an inner area (21) formed by the intermediate area (14) and the sealing lip (10, 10′) and an outer area of the sealing lip (10, 10′) can be glued to the covering surface (F) of the carrier (20, 20′, 20″).
