In an arrangement for sealing a housing with a cover, the cover includes a central hole for holding a gasket for a shaft which extends through the gasket in the installed state, and at least first and a second hollow-cylindrical protuberances which project roughly in the direction of the shaft relative to the areas of the cover which directly surrounds them. The protuberances are adapted to be inserted into the corresponding cavities of the housing. The peripheral surfaces of the first protuberance and its respective cavity are made to adjoin one another essentially without play and in an accurately fitting manner, and the second protuberance and its respective cavity are made such that the second protuberance can be essentially freely positioned within the cavity in the direction of a line which connects the two center points of the two protuberances and that the second protuberance is intended to adjoin at least one point of the peripheral surface of the cavity in the direction of the cavity diameter which is perpendicular to the line.
