A device to separate the links (M1, M2) of an ammunition belt, such belt exiting a weapon after firing and in which the links are mounted so as to pivot angularly with respect to one another, a relative pivoting position of a first link (M1) with respect to the following link (M2) enabling the first link to be unhooked, the device incorporating at least one tab integral with a support of the weapon and placed in proximity to the exit of the belt from the support, and able to make each link pivot with respect to the following one, wherein the at least one tab is placed above an exit of the belt, the at least one tab being pushed by the exiting of a first link (M1) against the action of a spring and which cooperates with a rear edge of the body of the first link (M1) to make it pivot with respect to the following link (M2), thus unhooking it. In alternative embodiments, the at least one tab is an elastic tab adapted to be deformed by the exiting first link.
