An end link for securing a watch strap on a watch case including a connecting piece of a wristband, the watch case having a pin. The case has a longitudinal slot delimited by two support surfaces parallel to a main plane. The connecting piece has a lateral face which includes a guiding groove arranged to cooperate in a complementary manner with the pin, and the connecting piece has a lock with a slide catch arranged to cooperate with the slot in a locking position, towards which the slide catch is moved by elastic return belonging to the lock. There is unlocking portion arranged to be operated directly by a user to move the slide catch away from said slot of the case. The guiding groove is curved so that the slide catch is firmly maintained against one of the two surfaces in the locking position.

The invention relates to an attachment device for two elements of a watch band to allow said two elements to be hooked into place or unhooked, wherein the first element comprises at least one bar on one of its ends. According to the invention the second element comprises two grooves, each comprising a longitudinal opening respectively opposite one another, and one of the two elements can move from an unhooked position, wherein one of the elements is oriented in a predetermined angular position in relation to the other element, to a hooked position, in which the two elements are coplanar after a rotation of a predetermined angle of one of the two elements in relation to the other so that each groove is articulated on the bar to hold the two elements hooked to one another.

A watch constituted by a case carried by a band, the case fastened on the band by a removable connection constituted by the interaction of two elements, a first element fastened on the band and a second element integral with the case. One of the elements is a hooking element while the other element is a locking element comprising a movable bolt biased by a resilient system, coupling it to the hooking element. The hooking element is constituted by a slider that interacts with a slide rail in the locking element, while the movable bolt comprises a locking projection engaged into a recessed profile on the slider. The movable bolt mounted in the locking element pivotingly around an axis is a class 1 lever including a first arm comprising the locking projection and a second arm biased by unlocking means.

In one aspect, the subject matter of the disclosure features a watch band. The watch band includes a strap and a clasp mechanism integrated with an end of the strap. The clasp mechanism includes a concave member defining a channel at the end of the strap and a cover plate. The cover plate is configured to move between (i) a first position in which the cover plate covers the channel, and (ii) a second position in which the cover plate is retracted to leave at least part of the channel uncovered by the cover plate.
