1. A three-point link comprising:
a central joint; and
two control arms that form an acute angle relative to one another and which simultaneously meet each other at one end in the central joint,
wherein the central joint has:
a cylindrical dome that extends in an axial direction extending at least substantially perpendicular to a plane defined by the two control arms having a circumferential groove;
a joint ball penetrated by the cylindrical dome;
a captive securing device functions as a stop and extends in a radial direction oriented perpendicular to the axial direction and is configured to prevent a complete separation of the central joint;
an annular securing element, wherein the captive securing device is penetrated by the cylindrical dome and is simultaneously secured against an axial withdrawal from the cylindrical dome by the annular securing element,
wherein, viewed in the axial direction, the annular securing element is arranged on a side of the captive securing device remote of the joint ball and engages in the circumferential groove of the cylindrical dome, and
wherein the annular securing element is snugly surrounded in radial direction by the captive securing device to prevent a withdrawal of the annular securing element from the circumferential groove of the cylindrical dome whereby the annular securing element cannot move out of the circumferential groove of the cylindrical dome in a radial direction.
