A ball-and-socket joint for a motor vehicle, especially for a rocker pendulum of a motor vehicle, is provided with a housing (), which is open on at least one side and into the interior space () of which a bearing shell () is inserted, which in turn accommodates a joint ball () of a ball pivot () in a slidingly movable manner. The interior space () has elevations and/or depressions () along its inner jacket surface () or a polygonal cross section, so that the bearing shell (), which is provided with an oversize in relation to the inner jacket surface (), can be inserted into the housing () in a positive-locking manner while its outer surface undergoes a partial plastic deformation. The inner jacket surface () may have pressure zones () which shorten the effective length of the elevations and/or depressions ().
