Claim 1:
2. A barrel for a barrel joint for parts of furniture and furnishing items comprising:
a hollow cylindrical body having a closed lower end surface, an open upper end and a side surface connecting the upper end to the lower end surface, the hollow cylindrical body containing a blocking element and having a hole defined in an upper portion of the side surface for passage of a tip of a tool, which actuates the blocking element, the hollow cylindrical body having, in a lower portion of the side surface, an additional hole for receiving a pin of the barrel joint, the additional hole having a diameter smaller than a height of the side surface, the hole on the side surface and the additional hole having parallel longitudinal axes both being perpendicular to a longitudinal axis of the hollow cylindrical body,
wherein the hollow cylindrical body rotatably houses the blocking element, the blocking element comprising a cylinder having an upper end having a peripheral toothing and a seat, and a lower end clamping structure comprising a cam in an intermediate portion thereof aligned with the additional hole and shaped as a curved wall, the cam being adapted to be engaged with a screw having an enlarged head forming part of the pin of the barrel joint to apply a clamping force on the screw, the cylinder being configured to be rotatable with a tip of a screwdriver that engages the cylinder on an upper face containing the seat or on a side thereof containing the peripheral toothing, and
wherein each of the open upper end and of the hole in the upper end portion of the side surface provide access for the tip of the screwdriver to the cylinder disposed in a housing portion of the hollow cylindrical body for rotating the cylinder by means of the seat or peripheral toothing and producing a clamping force on the screw.
