  • the present disclosure relates to a locking apparatus and, in particular, relates to an interchangeable locking apparatus in the form of a clasp for locking and releasing an end cap.
  • Jewellery manufacturers typically implement openable clasps to secure jewellery items, such as chains and bracelets in position.
  • Such clasps include a plate or hook to hold the chain, bracelet, bangles, and the like, in position, which can be opened with the help of hinges provided within the clasp. The hinges may break if excess force is applied while opening the clasp.
  • a conventional clasp includes two slots for receiving a chain, which is to be secured using the clasp.
  • the slots are in a closed position and for securing the chain using the clasp, the slots need to be opened.

  • the other side of the chain is then placed in the other slot and closed.
  • the aforementioned mechanism of securing the chain using the clasp becomes annoying if the user has to change the clasp or the chain often.
  • beads or charms are placed on the chain from the openable side of the chain; the other side of the chain is fixed in the other opening of the clasp.
  • the beads generally have a threading within them to screw them onto the chain.
  • the ends of the chain have a threading for the beads. If the chain is filled with beads and the user needs to remove the bead that was first put on, the user has to remove all the other beads by unscrewing each one till that bead is removed since it was at the end of the chain where the chain is fixed into the clasp. This process may become tiresome whenever a bead needs to be replaced or removed for another bead. Further, to keep the beads in a specific area of the chain, clips are normally used to secure the beads to one area of the chain. The clips also operate in the same manner as the clasp.
