A tool is provided that includes a plurality of links including at least three links movably interconnected to one another to form at least a portion of a wearable accessory, such as a bracelet. The plurality of links are articulatable so as to alternately assume a first configuration in which the plurality of links extend linearly, a second configuration in which the plurality of links are curved about an axis in a first direction and a third configuration in which the plurality of links are curved about the axis in a second direction, opposite the first direction. The plurality of links are configured to permit limited motion in a direction parallel to the axis prior to becoming structurally rigid. At least one link includes at least one tool function. A clasp and a receiver are also provided to facilitate the functionality and versatility of the resulting wearable accessory.

Clasp comprising a cover connected to a first bracelet strand and to a second bracelet strand, a connecting means being inserted between the second bracelet strand and the cover of the clasp, the connecting means comprising an end link sliding between a first position in which it is engaged in the cover of the clasp, and a second position in which it is outside the cover of the clasp, the end link comprising a push-button which causes a toothed element to change from a first position, in which the toothed element is in mesh with a rack toothing, to a second position, in which the toothed element is released, the end link being provided with an arresting means preventing the removal of the end link from the cover of the clasp, the arresting means comprising at least one lug, which projects into a groove arranged in the bottom of the cover and which defines two end stop members.

A clasp includes a lower holding member in which a lock pin is fixed, an upper holding member which is pivotably interlocked with the lower holding member, a lifting member which is attached to the lower holding member so as to be able to move in a lifting direction and a lowering direction and guides a first band, a lock member which is attached to the lower holding member so as to be able to pivot between a lock position and an unlock position, and a main cover. The lock member lifts the lifting member to the lower holding member side when being pivoted to the lock position so as to perform positioning and fixing of the first band while interposing the first band therebetween.

The invention relates to a bracelet clasp, in particular for a wristwatch, comprising a device for fine length adjustment of the bracelet. In one embodiment, the invention relates to a clasp with extensible buckle, and the adjustment device is provided on a blade intended for being inserted between two posts of a main blade when the clasp is closed. The adjustment device includes a locking pin, arranged in an orthogonal direction relative to the longitudinal direction of the clasp and housed so that at least one portion of the pin is provided above a common upper surface of the blades of the clasp. In one embodiment, the mobile piece of the adjustment device is pivotably mounted on the clasp.

Connecting device allowing a releasable connection between a bracelet strap and a folding clasp including at least two articulated arms and two fastening portions capable of reversibly cooperating with each other. The connecting device includes a first connecting piece capable of being secured to the free end of the bracelet strap and a second connecting piece capable of being mounted on the fastening portion. The first connecting piece and the second connecting piece are configured to reversibly cooperate with each other between a first, open position allowing separation of the first connecting piece and the second connecting piece and a second, closed position in which the first connecting piece and the second connecting piece are locked together.

A watch clasp with a finely adjustable watch strap length includes: a watch clasp sliding holder, located on a back surface of a watch clasp case; a sliding stop module, fixing the watch clasp sliding holder to the back surface of the watch clasp case through engagement, where the sliding holder can slide between the watch clasp case and the sliding stop module; a stop spring bar, fixed to the watch clasp case, and an unlock module, fixed to the watch clasp case where the unlock module is engaged with the sliding stop module, and the stop spring bar and the unlock module are respectively located on two sides of the sliding stop module; and an extension latch assembly, where one end of the extension latch assembly is fixed to the watch clasp case, and another end of the extension latch assembly is fixed to an elastic fine-adjusting assembly.
