Abstract
Abstract A device for rigidly interconnecting wood panels or other parts of a piece of furniture. The joint comprises a finned shank and a head, secured within a seat provided in a first panel, and the head being removably engageable with a pin projecting from a second panel to be connected to the former. The joint head comprises a seat coaxial with the shank, and open at the front and top for introducing the pin from above; on the bottom and at intermediate position, the seat in the joint head also has a transverse rib for engagement with a slot at the pin end. A closure cover clamps the pin in the seat and has projecting tabs for rotational engagement within longitudinal slots provided internally of the head at the top of the rib.
