Ball joint

A ball joint (10) for a wiper system, the ball joint comprising a ball shell (12), a ball head (14) within the ball shell (12), a hinged rod (16) into which the ball shell (12) is inserted and a securing means (18), wherein the hinged rod (16) is elongated in an axial direction (1), wherein the securing means (18) defines two opposing U-shaped cross sections in a first plane perpendicular to the axial direction (1), wherein the hinged rod (16) extends into the opposing U-shaped cross-sections, and wherein the securing means (18) engages around the hinged rod (16) in order to reduce an opening (20) in the ball shell (12) to a blocking distance (d), such that the ball head (14) cannot be removed from the ball shell (12);

• wherein the securing means (18, 181) is groove-shaped and has a third U-shaped cross section in a second plane perpendicular to the first plane and perpendicular to a direction of insertion of the ball head (14) into the ball shell (12) and two limbs (26) connected together at a connection at one end, wherein each of the limbs (26) forms a respective one of the opposing U-shaped cross-sections in the first plane, wherein the limbs (26) and the connection form the third U-shaped cross-section, and wherein the connection engages around an axial end (30) of the hinged rod (16).
