Abstract
An elongated semi-product from which a clasp can be formed includes at each end at least one through-penetrating hole wherein when bent to form said clasp the semi-product forms a generally closed cavity with the mutually opposite ends of said product forming overlapping legs and the openings at the ends of said semi-product being intended to coincide in one position of the legs to enable said stem-part to be inserted easily through the two holes in said legs, wherein in another position of said legs the holes provided in the edge regions of the ends of said legs will be pressed against a portion of reduced diameter on the stem so as to hold an ornament in place. According to the invention, at least one of the two opposing openings in the semi-product has an elongated and irregular shape so as to include at least two holes of different sizes, and at least one opening extends transversely to the longitudinal axis of the semi-product.
