The technical area of the invention lies in the production of jewellery. The ear-stud securing means hitherto on the market undo themselves, as a result of which the ear-stud is generally lost. Solution of the problem: On sliding on the novel securing means two claws snap at an angle of 90 DEG into the notch of the pin and rule out the possibility of the stud becoming undone. The securing means can only be undone by actuating the spring (see drawing). Use of the patent: Suitable for all ear-studs. <IMAGE>
