Bracelet latch having an extensible buckle

A bracelet latch with an extensible buckle comprising a cap defining a housing and having a first slide-way in which a first slide is engaged, the first slide being designed to be connected to a first strand of a bracelet by a first articulation means, the first slide includes at least first segment and second segment connected to one another by a second articulation means, said first segment and second segment being at least partially folded in the housing when the buckle of the bracelet latch is not extended,

• wherein said bracelet latch also comprises a first indexing means for indexing the first slide in the cap such that the first slide, relative to the cap, can occupy a series of indexed positions comprised between:
• a first extreme position in which the first slide is situated in the housing such that ends of the bracelet latch are at a minimum distance, and
• a second extreme position where the first slide is partially situated outside the housing and where the first segment of the first slide is situated entirely outside the housing,
• said first slide being kept folded in the housing by the cap in all positions, except the second extreme position, only in which position can the first segment and second segment of the first slide be extended and the ends of the bracelet latch can be brought to a maximum distance, and wherein the first indexing means comprises a first actuator and a first maintenance device to block the different indexed positions,
• wherein said first actuator is arranged to transmit a force making it possible both to free the maintenance device so as to unblock an indexed position, and
• wherein said first actuator is further adapted to move the first slide longitudinally relative to the first slide-way.
