A bomb fuze arming clip made of spring steel and having a substantially triangular or loop shape. A first side of the triangle extends for some distance through a hook in which the end of the third side is formed. The clip is made of spring steel. Downward force on an apex of the triangle forces the extending portion of the first side of the triangle downward through the hook, thereby opening the clip.
