Abstract
A ball joint having first and second articulated coupling parts having interconnected liquid ducts. The second coupling part is held pivotably by a spherical front end region between a shape-adapted joint socket on the first coupling part and a joint head on a holding element in the inner cavity of the second coupling part. The holding element interconnects the liquid ducts, and the second coupling part has, on its inner wall delimiting the inner cavity, an annular groove with a ring seal. A first annular shoulder is on the inner wall of the second coupling part, an annular insert part is insertable into the inner cavity of the second coupling part, and the insert part is spaced apart from the first annular shoulder such that the spacing between the first annular shoulder and the front edge of the insert part facing the first annular shoulder forms the annular groove.
