Abstract: Joint for frames of furnishing elements consisting of a plurality of components (11, 12, 13) joined together. The joint comprises a plane platelet element (15, 115), lying during use on a first plane. The plane platelet element (15, 115) has on the perimeter attachment teeth (20) which are inserted inside apertures (25) present on at least a first component (13) in order to clamp the first component (13) and the joint (10). The plane platelet element (15, 115) is associated with a back (14b, 31) lying on a plane angled with respect to the first plane on which the plane platelet (15, 115) lies, the back (14b, 31) bearing a hole (17, 117) for the passage of attachment means (29) which anchor on a second component (12) to be attached to the first component (13).
