The invention relates to a device for a ball-and-socket-type connection of two members. Said device including a first member and a second member, which are interconnected by a ball-and-socket-type articulation; the first articulation segment is configured on the first member as an articulation head and the second articulation segment is configured on the second member as a cavity that receives the articulation head; the cross-sectional surface of the cavity being tapered at the lower end of the second member as a result of a constriction; at least one of the articulation segments in the contact area of the latter is configured spherically with a center of articulation Z; the ball-and-socket-type connection between the two articulation segments can be detachably fixed by means of a clamping element that can be connected to the second articulation segment; the articulation head has a recess, in which the front end of the clamping element can rest; the recess and/or the front end of the clamping element has an at least partially spherical surface with a centre C; and in the clamped position of the device, the center of articulation Z and the centre C are identical.
