For an articulated attachment between a traction vehicle and an implement, ball-and-socket joints are provided at the articulation points of the attachment device and are pushed onto bearing pins of the implement and subsequently pinned. As a function of the size of the implement, the bearing pins are divided into two categories, which also makes adaptation of the spherical bodies in the ball-and-socket joints necessary. In order to achieve simple adaptation of the spherical bodies (2, 3) to the respective bearing pins, the latter are easily interchangeable. After the spring plug (4) is released, all that is necessary is to rotate the shell (5) manually through 90@ within the half shell (8). The shell (5) can be subsequently removed laterally from the lower link 1, as a result of which the ball-and-socket joint (15) is exposed and the spherical bodies 2, 3 can be interchanged. The attachment device, component of a three-point linkage, serves on agricultural machines, in particular tractors, to bring about coupling between implement and tractor (Fig. 5). <IMAGE>
