The sealing element has a closed lateral portion and a closed cover portion adjoining the lateral portion in the axial direction, wherein the lateral portion circumferentially encloses the shaft of the blind rivet element at least in the region of the deformation portion, and the cover portion is formed at an end of the shaft of the blind rivet element facing away from the head portion.
