Abstract Improvements in or relating to Safety Devices for Carrier Shells A safety device for a carrier shell of the type comprising a shell casing (2), a plurality of secondary projectiles (7) and an explosive dispersal charge (47) for dispersing the secondary projectiles is capable of preventing undesired dispersal of the projectiles before the shell is fired. The safety device provides first and second restraining means for restraining relative movement between the body (15) of the safety device and the shell casing. The first restraining means (25) is releasable by detonation of the explosive dispersal charge to allow the exit of the body of the safety device from the shell and the venting of the dispersal charge through the aperture left therein. The second restraining means (33) is actuable to restrain relative movement between the body and the casing and is capable of withstanding the detonation of the explosive charge.
