  • the beak 10a and/or the front portion 23a may comprise an inclined slope or a chamfer in order to facilitate the insertion of the beak 10a into the shoulder 23b.
  • the lock 10 further comprises a housing 10b, preferably circular, in order to house the pivot part 22.
  • the lock 10 can thus tilt (or pivot) along a tilting axis B, perpendicular to a fixing axis F of the fixing interface 21.
  • the lock 10 can be installed on the pivot part 22 by sliding the lock 10 into the pivot part 22 along the tilting axis B and then be introduced into the jewelry item 100 along the fixing axis F.
  • the screw 21 can then be screwed into the thread of the pivot part 22.
  • the pivot part 22 is thus assembled at a radial portion and not at its ends.
  • the lock 10 is therefore mounted on a side face of the jewelry item 100 and is therefore at least partially hidden, and thus has the advantages mentioned above.
  • the latch 10 further comprises a protrusion 10c in order to cooperate with an elastic return element 20, such as a coil spring or helical spring.
  • the spring 20 makes it possible to return the latch 10 to the closed position.
  • the protrusion 10c is arranged opposite the beak 10a.
  • the housing 10b is arranged between the protrusion 10c and the beak 10a.
