ABSTRACT:
In order that it may be simple in use and of robust composition it has been constructed with a case (1) sliding round a coupling-piece (2) of which one end is connected to a small chain (6) and the other has a loop (3) which forms an opening (4) which in contact with the outside is in the open position or if not is in the closed position. In addition a leaf spring (8) is housed in the coupling-piece (2) and cooperates with a stud (9) which is integral with the case (1) in order to ensure by sliding of the case (1) and by elastic deformation of the leaf spring (8) the open or closed position.
