Claims

1. A bracelet or wristband of adjustable length, characterized in that it includes: a first link including two ends defining first and second fixed points of attachment,a stopper including a through hole that allows said link to pass therethrough, releasable means for locking the link in said hole, and means for securing one of the ends of said link, anda securing element associated with said first point of attachment, said link being on one hand secured to the stopper by said second fixed point of attachment using said securing means, and on the other hand engaged in said hole so as to be able to be locked at a variable locking point, by said locking means, or to slide therein when said locking means are released, and said link further comprising, a variable point of attachment located substantially half-way between the second fixed point of attachment and the variable locking point.

2. The bracelet or wristband according to claim 1, wherein said locking means include a hole and an end portion to be fitted to the end of a link, said hole and said end portion being provided with radial and axial positioning means for the end portion inside the hole.

3. The bracelet or wristband according to claim 2, wherein said positioning means are formed of a circular groove extending from the bottom of said hole and a shoulder located at the end of said end portion.

4. The bracelet or wristband according to claim 1, wherein said securing element includes means of attachment to said first point of attachment and to said variable point of attachment.

5. The bracelet or wristband according to claim 1, wherein it further includes a second link secured to said first link by said variable point of attachment, such that relative sliding of said first link to said second link is possible.

6. The bracelet or wristband according to claim 5, wherein said second link forms, with said first link, a flat knot at said variable point of attachment.

7. The bracelet or wristband according to claim 5, wherein said second link includes two fixed points of attachment located at the two ends thereof.

8. The bracelet or wristband according to claim 5, wherein it further includes a clasp, the ends of said second link being secured to said clasp.

9. The bracelet or wristband according to claim 8, wherein it further includes a third link including a point of attachment to said clasp.

10. The bracelet or wristband according to claim 9, wherein said first link is secured to a case by said first fixed point of attachment using a securing element, and wherein said third link is also secured to said case using a connecting part so as to form a wristwatch.

11. The stopper including a body provided with a first through hole having an axis BB able to allow a link to pass therethrough, and releasable means for locking the link inside the hole, wherein it further includes securing means for the end of a link.

12. The stopper according to claim 11, wherein said securing means are formed of a blind hole and an end portion to be fitted to the end of a link, said hole and said end portion being provided with means for the axial and radial positioning of the end portion inside the hole.

13. The stopper according to claim 12, wherein said positioning means are formed of a circular groove extending at the bottom of the blind hole and a shoulder located at the end of said end portion.

14. The stopper according to claim 11, wherein said locking means include a housing, a piston and a spring, said piston being mobile inside the housing over a limited travel, and pierced with a second hole of parallel axis to axis BB, said spring abutting on said piston so as to exert a force tending to expel it from said housing and said second hole being coaxial to said first hole on one point of the travel of said piston.

15. The stopper according to claim 11, wherein said locking means include a housing, a piston and a spring, said piston being mobile inside the housing over a limited travel, and including a recess of parallel axis to axis BB, said spring abutting on said piston so as to exert a force tending to expel it from said housing, said recess partially closing said first hole over one portion of the travel of said piston and being coaxial to axis BB at one point of the travel of said piston.
