A ball coupling for reliable connecting and releasing floating pipings of mud ships and the like nautical applications, mainly consisting of an outer ball a hollow inner ball, and a retaining member, has according to the invention been improved by embodying the retaining member in the form of pivotable ring segments which are located in a space which is delimited by flanges positioned perpendicular to the center line of the outer ball. Hereby it is achieved that the retaining means is at a fixed place due to which coupling and uncoupling of pipings can be executed much easier and quicker.
