Abstract: A clasp for a bracelet enabling the bracelet length to be adjusted with the clasp closed. The clasp has first and second leaves pivotably connected relative to one another at a first end. A cover pivotably connects a second end of the first leaf to be connected to a first strand of the bracelet. A mobile tip is arranged on a second end of the second leaf to connect to a second strand of the bracelet. The clasp has an indexing mechanism for adjusting the length of the bracelet and a release arranged such as to enable the mobile tip to move from one indexed position to another. The second leaf ends in two rectilinear rails along which the mobile tip can slide. The indexing mechanism is located on a rail of the second leaf while the release mechanism is arranged to move together with the mobile tip.

Abstract: An extensible clasp or buckle for a wrist strap, which makes it possible to control the length of the wrist strap. The clasp has a first and a second strip which are articulated to one another at a first end, and a first tie which is arranged at a second end of the first strip for connection to a first strand of the wrist strap. The clasp also has a second tie which is arranged at a second end of the second strip for connection to a second strand of the wrist strap, and a way to displace the second tie with respect to the end of the second strip in order to adjust the length of the wrist strap. The second tie is connected to a cradle which is arranged in a housing located on the second strip. The housing has two opposite walls along which the cradle can slide. The clasp also has a tab which is connected to the second strip and arranged so as to cooperate with the cradle.

Abstract: The present invention concerns a clasp with an extensible buckle for a bracelet enabling the length of the bracelet to be adjusted. This clasp comprises: a central support (1); a first and second pivoting strip (2a, 2b) articulated at the respective ends of the central support (1) and capable of being closed on the latter; means for closing and opening (14, 16, 17, 19, 22) the clasp arranged in such a way as to lock the first and second pivoting strip (2a, 2b) against the central support (1) and to unlock said first and second pivoting strip (2a, 2b) of the central support (1) so they can be extended; at least one first attachment (6a) solid with the first pivoting strip (2a), and arranged to be connected to a first strand of the bracelet and a second attachment (6b) solid with the second pivoting strip (2b) and arranged to be able to be linked to a second strand of the bracelet.

Abstract: The invention relates to a clasp comprising an extensible buckle for a wrist strap making it possible to control the length of the wrist strap. For this purpose, the clasp comprises: a first and a second strip (10, 11) which are articulated to one another at a first end; a first tie (12a) which is arranged at a second end of the first strip (10) for connection to a first strand of the wrist strap; a second tie (13) which is arranged at a second end of the second strip (11) for connection to a second strand of the wrist strap; and means for displacing the second tie (13) with respect to the end of the second strip (11) in a manner to adjust the length of the wrist strap. The second tie (13) is connected to a cradle (16) which is arranged in a housing (17) located on the second strip (10). The housing (17) comprises two opposite walls (18, 18?) along which the cradle (16) can slide.

Abstract: The invention relates to a coating composition for a metal substrate exhibiting a free outer surface consisting of a metal coating based on zinc or a zinc-based alloy, characterized in that it comprises: silicate(s) of sodium and/or potassium and/or lithium (3-35 wt. %), a tensioning agent (à.01-1 wt. %), the remainder being water in a quantity sufficient to arrive at 100 %.
