Fastening device by pneumatic fastening essentially characterized by consisting of a conical bell body open by its base to which a disc-shaped element fitted on one of its faces with a circular rib of smaller diameter than the disc defining an outer circular crown by the which is coupled together with the outer edge of that rib to the mouth of the conical bell forming a pneumatic chamber whose effective volume has two extreme values, the minimum value corresponding to a position of deformation of the essentially elastic disk towards the interior of the bell forming a empty space between the outer face of the disc itself and the supporting surface of the device.
