Abstract: Disclosed are sealing or corrugated bellows for sealing two parts (1, 2) that are movable relative to one another. Said sealing or corrugated bellows comprise two spaced-apart edge regions (4, 5) which are connected by means of a jacket (3) and in each of which one clamping element (6, 7) is embedded. According to the invention, the jacket (3) has several internal diameters (d2, d3, d4) that have different sizes. The internal diameter (d1) of one of the edge regions (4, 5) of the sealing or corrugated bellows (8) is greater than the largest of the internal diameters (d2, d3, d4) of the jacket (3) of the sealing or corrugated bellows (8). Such sealing or corrugated bellows can be used particularly for a ball-and-socket joint in a motor vehicle.
