Abstract: A device for the rapid attachment of an interchangeable watch bracelet for wrist watches, as well as a wrist watch and an interchangeable watch bracelet. A body used as a push button slidingly housed in a watch case includes a retaining stem arranged parallel to the watch case. The body is displaceable parallel to a longitudinal axis of the retaining stem and the body is biased in a rest position. The device includes an attachment element mounted at one end of the interchangeable watch bracelet, comprising a slot with a shape complementary to that of the retaining stem. The retaining stem is thus adapted, depending on its position along the longitudinal axis, to cooperate with the attachment element or elements so as to enable the interchangeable watch bracelet to be attached to or to be removed from the watch case.
