Abstract

A safe-and-arm or securing device for the fuze of a spinning or spin-stabilized projectile which includes a fuze member and a supporting member in which a spherical rotor is rotatably supported, and which has a radial groove formed therein. The rotor possesses a bore having a detonator inserted therein, and in a peripheral region incorporates a groove which extends along a plane which is axially offset relative to the radial groove, and with a spreadable or expandable restraining medium being inserted into the groove. The restraining medium releases the rotor which is retained in its secured position only subsequent to the firing of the projectile through the securing element which is spreadable and axially displaceable under the effect of axial and spin forces and which allows the rotor, after its release, to be pioted in conjuction with the detonator into the armed position.
