Abstract
The invention relates to an attachment device with a fastener, a first supporting disk and a second supporting disk, wherein the fastener has a head with a head contact surface and a pin extending out along a longitudinal axis, wherein the pin has an attachment end with a contact surface that is opposite the head contact surface. The first supporting disk has a suitably large opening to permit the pin to pass through the opening, and has a wedge-shaped section. The second supporting disk has a suitably large opening to permit the pin to pass through the opening and to permit the second supporting disk to turn relative to the fastener about the longitudinal axis of the pin. The second supporting disk is in contact with the wedge-shaped section and moves along the surface of the wedge-shaped section, when the second supporting disk and the fastener turn relative to each other about the longitudinal axis of the pin.
