The protector includes a membrane (3) which has the characteristic that it breaks as the result of the pressure which builds up in the weapon barrel when firing takes place. The membrane has a central area (6) which reduces strength. Several breakage indicating tracks (7) emanate radially from the central area. The central area, as a result of the weapon being fired, breaks. After this, the tracks break and form flaps which are held together against the collar (1). |
