Abstract
A device for fastening interchangeable watchstraps with sliding lock mechanism, in particular for a watchcase, including a middle (1) and two pairs of horns (2), each horn being provided on its inner face with a skid (8) with one bevelled edge and a gap (10). Each watchstrap strand (3) includes a first link (4) on the lateral faces of which are found two grooves (5) adapted to the shape of the skids (8). Each groove contains a pin (6) connected to a head (7) and to a spring. The fastening takes place when the skids (8) engage in the grooves (5) of the first link (4) until locking of the pins (6) in the gaps (10). The watchstrap can be released by acting on the two heads (7) which retract the pins (6) from the gaps (10), making it possible to withdraw the watchstrap strand (3).
