Abstract: A hinge wing includes a cup intended for being fixed in a hole of a furniture component. The wing is provided with a pair of expandable teeth arranged on opposite sides of the cup. The teeth are fixed on an eccentric lever of the wing, by rotating which the teeth are moved in an opposite direction to the direction of insertion of the cup into the respective receiving hole. The wing includes for each tooth a cam that, upon rotation of the eccentric lever, causes the respective tooth to expand against a side wall of the receiving hole of the cup to fix the cup to the furniture component. Each cam is formed with a cam element of yieldable material interposed between a side wall of the cup and the respective tooth.
