<p>A protective bellows (6) has a fixing collar (20) at one of its ends, for fixing over the casing of a universal joint or the like which has a slightly greater diameter than the internal diameter of the fixing collar (20). To facilitate the necessary stretching of the material of the bellows for the fitting process, the axially leading edge of the bellows is formed with peripherally arranged teeth (26). <IMAGE></p> |
