• and
• a connection group adapted to be attached to the second panel,
• wherein the blocking group is adapted to be inserted inside a longitudinal seat defined in a thickness of the first panel and extending perpendicularly to the approach direction, the blocking group being configured to be actuated from at least one side of the seat,
• wherein the blocking group comprises,
• a threaded screw having a head shaped as a toothed crown and a threaded stem extending from the head,
• a grub screw engaging the threaded stem, and
• a casing housing an entirety of the threaded screw and the grub screw,
• wherein the connection group comprises a pin having a first end and a second end, the second end being threaded and adapted to engage a threaded bush disposed within the second panel,
• wherein the casing has a first opening configured to receive a tool engaging the toothed crown, and a second opening longitudinally aligned with the first opening and configured to receive the first end of the pin,
• whereby a rotation of the toothed crown causes a longitudinal movement of the grub screw toward or away from the pin, so as to engage or disengage the pin.
