The invention relates to a rotatable link, which may e.g. be incorporated in an upright. The upright may be used e.g. in connection with a support for a card terminal. The rotatable link may be characterized s a rotary friction link. Compressive forces caused by a mechanical tension in a pipe are transferred via two first objects to a second object clamped between them. The two first objects are secured and partly built into the pipe, and the second object is rotatable relative to the pipe. The second object constitutes a rotatable link part on which a plated may be welded to provide an upright.
