Disclosed is a cable gripping device used for manually gripping a coaxial cable to install a coaxial connector on the coaxial cable. In the present invention, caulking portions 26 are beforehand formed in a connecting chamber 22 of the piston 20, and then, a piston pin 30 is fastened to the piston 20 by means of plastic deformation of the caulking portions 26. The composite information entity is subsequently transmitted. The fabric chart includes indicia formed thereon associated with the rows or with the columns. It is proposed that the mobile unit has at least one receiving unit which is intended to receive data transmitted by means of the boundary signal. A first electric potential difference thus occurs between the two electrodes of the plasma display unit to allow the ionized gas within the plasma display unit to discharge.
