A clamp including two mutually opposed substantially L-shaped members pivotably connected to an intermediate holder supporting the side profile sections of the panel frames to be secured, wherein one of the arms of each of the L-shaped members has a shaped end portion suitable for coupling to the sections to be secured, whereas the other arm of each of said L-shaped members is rotated by a mechanism built into the intermediate holder so as to open and close the L-shaped members of the clamp. |
