ABSTRACT:
A fastening element for fastening hardware elements (31) to parts of furniture units (14) comprises an expansion plug (11) having an axial through housing (17) which can receive an expanded pin (23), which can rotate between a position in which the plug is not expanded, to enable it to be inserted in a hole (16) in the furniture unit (14), and a position in which the plug is expanded to anchor it in the hole. The walls of the axial housing (17) and of the pin (23) have reciprocal contacting surfaces in the expanded position which diverge in the direction of insertion of the plug. A cam plate (32) provided centrally with a polygonal hole (33) for coupling with a protrusion (30) of the pin (23) and peripherally with a raised edge (34) for guiding fingers (22, 22') of the plug (11) for reversibly guiding the expansion of the plug.
