<p>The invention relates to a locked pressure closure system for earrings, consisting of an essentially-cylindrical pin (2) which is fixed at one end to a decorative piece (1) and a pressure part (3) comprising at least two transverse flanges (5) which are positioned facing one another such as to define a through hole in which the pin can be inserted. The pin (2) includes a longitudinal segment having a non-cylindrical cross-section close to the end opposite the decorative piece (1). The shape of the aforementioned through hole complements that of the non-cylindrical segment of the pin (2), such that, when the pressure part (3) is placed on the non-cylindrical segment of the pin, the two elements are offset in relation to one another and locked together.</p> |
