Device for finely adjusting the length of a bracelet and a bracelet comprising at least one such device

A device for finely adjusting the length of a bracelet, intended to be inserted between two elements of the bracelet and comprising:

• an outer part arranged to be attached to one of the two elements,
• an inner part arranged to be attached to the other element and to slide in the outer part parallel to the longitudinal direction of the bracelet so as to cause the length of the bracelet to be varied, and
• stop means arranged to limit the travel of the inner part relative to the outer part so that the bracelet cannot be extended beyond a maximum length,
• wherein the outer part further comprises a wall having at least one immobilization hole on its inner side, the inner part comprising hooking means arranged to cooperate with said at least one immobilization hole so as to immobilize the inner part with respect to the outer part in at least one relative position,
• wherein the hooking means comprise a first end arranged to cooperate with said at least one immobilization hole to fixedly attach the inner part and the outer part together, and wherein the inner part comprises a control member which can be actuated manually to detach the inner part from the outer part,
• wherein the inner part comprises a removable auxiliary stop arranged to cooperate with an edge of the outer part so as to limit the travel of the inner part relative to the outer part so that the bracelet cannot be shortened to less than a minimum length,
• wherein the inner part has two bores arranged on either side and opposite each other, and
• wherein the auxiliary stop comprises at least one fixing arm provided with a through-hole arranged coaxially between the two bores, the auxiliary stop being fixed to the inner part by means of a pin orientated perpendicularly to the length of the bracelet and inserted through the through-hole and the two bores.
