1. A safety device for a percussion fuze of a projectile, having a firing pin (4) and a spring-brased slide member (10) transversely movable between a safety position and a firing position, in which the firing pin (4) impacts on a primer capsule (11) carried by the slide member (10), said safety device comprising a first locking mechanism (17) holding said slide member (10) in the safety position and responsive to projectile acceleration to release the slide member for movement to said firing position, a manually releasable locking device (25, 26) holding the firing pin (4) in contact with said slide member (10) to retain it in the safety position, with a blind bore (13) in the slide member (10) in which the firing pin (4) in its safety position enters for preventing that the slide member (10) moves in the firing position, characterised in that : the blind bore (13) of the slide member (10) is covered by a locking device (30), comprising an aperture (31) and a narrow longitudinal slot (32) and in that the firing pin (4) having a restricted portion (33) which is adapted to engage in the slot (32) to prevent complete withdrawal of said firing pin (4) from said slide member (10) if the slide member (10) is not secured by said first locking mechanism (17) and in that the aperture (31) of the locking device (30) is adapted to release the firing pin (4) if the slide member (10) is secured by said first locking mechanism (17) in the safety position. |
