A seal for sealing component openings in components of a means of transport, in particular for sealing openings in aircraft airfoils and tail units, comprising an inner cover connected to an outer cover via connecting members. An insert may be arranged in the component opening the outer cover being at least locally adjacent to an insert outer surface, and the inner cover being at least locally adjacent to an insert inner surface. Due to the insert arranged in the component opening, manufacturing of the seal, e.g., by an injection molding technique, may be possible, producing already at manufacturing level a high surface quality of the resulting sealing surfaces between the insert, the inner cover, as well as the outer cover.
