Abstract: A clamping system (10) for connecting a display device (26) to a support (25), includes a body (11) adapted to be connected to the display device (26), a clamp (12) for connecting the clamping system (10) to the support (25), a closing device (15, 16) for closing the clamp (12) when connecting the clamping system (10) to the support (25), the closing device (15) being integrated in the clamping system (10). The clamping system also may include a clamp opening device (14) for keeping the clamp (12) in an open position when not in use. A clamping system (10) may be a one-piece system and is easy to use and to handle. A method is described for connecting a display device (26) to a support (25), a display device system (30) including a display device (26) connected to a support (25) using at least one clamping system (10) according to embodiments of the invention and a method for making such a clamping system (10).
