Abstract
An expansion fastener for hardware elements for furniture comprises an externally ribbed anchor (,) in which an insert (,) is fitted, which insert has a cam surface (,) sliding on a corresponding cam surface (,) in the anchor body for causing a radial expansion of the anchor when the insert is moved by pulling means (,). The insert (,) comprises a fitting end (,) extending radially in a region free from the anchor body and is secured to the pulling means to be susceptible of inclination in the extension direction of said end (,). On axial movement towards the expansion position, the insert slides on the cam surface to receive a thrust for inclination and move said end outwardly of the anchor and towards the pulling direction.
