Claim 0:
1. A barrel for a barrel joint for parts of furniture and furnishing items comprising:
a hollow cylindrical body having a closed lower end, an open upper end and a side surface connecting the upper end to the lower end, the hollow cylindrical body containing a blocking element and having, on a lower portion of the side surface, opposing through holes with a common longitudinal axis perpendicular to a longitudinal axis of the hollow cylindrical body for receiving a pin of the barrel joint, and further having an internal threading, in which the blocking element is screwed, the blocking element comprising a grub screw comprising an upper end having a peripheral toothing and a lower end having a clamping surface, the grub screw configured to be screwed to move along the longitudinal axis of the hollow cylindrical body to apply a clamping force on the pin of the barrel joint,
wherein the hollow cylindrical body has an additional hole in an upper portion of the side surface and spaced from the open upper end, for passage of a tip of a tool adapted to act on the peripheral toothing of the grub screw to screw the grub screw toward the opposing through holes to apply a clamping force on the pin of the barrel joint, the additional hole being positioned so as to provide the tool with access to the toothing and to enable the screwdriver to engage the toothing, and
wherein the open upper end of the hollow cylindrical body enables passage of a tip of a screwdriver adapted to be inserted in a housing portion of the hollow cylindrical body containing the grub screw to actuate the grub screw and apply a clamping force on the pin of the barrel joint, the opposing through holes having the longitudinal axis that is offset from a longitudinal axis of the additional hole.
