The invention pertains to a ball joint comprising a housing (1) provided with a cylindrical receptacle opening (1a) and a gudgeon (2) arranged in a ball socket (3) made of plastic such that it is able to rotate and pivot within a limited range, wherein the outer surface (3b) of the ball socket that corresponds with the inner diameter of the receptacle opening (1a) is, after the assembly process, fixed in the radial direction and secured in the axial direction by means of annular shoulders (3c,4a), one of which (3c) is situated on an annular flange that surrounds the opening (3a) of the ball socket (3) on the side of the gudgeon. In order to ensure a secure, i.e., large-surface, fixing of the ball socket (3) on the housing (1) in the axial direction despite a simplified manufacture, the annular shoulder (4a) that cooperates with the upper side of the housing (1) is arranged on a ring (4) connected with the ball socket (3), preferably in an inseparable manner by means of ultrasonic welding.
