A sliding hook for clasping pearl or similar jewelry necklaces that have both a free and a fixed end including a body having a rear side, a ring of a substantially open turn shape disposed on the body so as to allow for slightly oblique passing of the free end of the necklace, a joining point disposed on the rear side of the body for affixing the fixed end of the necklace, and an articulated annular blade having legs with tension and disposed on the rear side of the body so that the tension of the legs applied against the ring retains the pearl that is disposed between the ring and the annular blade and thus determines the length of the hanging free end of the necklace being passed through the ring. |
