Abstract
A device for a ball-and-socket-type connection of two members includes a first member having a head and a second member having a cavity that receives the head. The cross-sectional surface of the cavity is tapered at the lower end of the second member as a result of a constriction. The head and/or cavity is configured spherically with a center of articulation (Z). The ball-and-socket-type connection between the two members can be detachably fixed by means of a clamping element that can be connected to the second member. The head has a recess in which the front end of the clamping element can rest. The recess and/or the front end has an at least partially spherical surface with a center (C). In the clamped position of the device, the center of articulation (Z) and the center (C) are identical.
