The ball joint comprises a first, substantially rod-like component, which has a ball head; a second component, which has an insertion opening, which narrows in funnel-like fashion in the area of its beginning and is provided with an annular groove spaced apart from the beginning, a radially elastic securing ring, which is insertable into the insertion opening and lockable into place in the annular groove, as well as a sleeve, which has an annular groove for receiving the securing ring during the insertion into the insertion opening until it locks into place in the detent provided by the annular groove of the outer component. The sleeve surrounds the ball head in an articulated and undetachable manner.
