A hollow controlled fragmentation head for an explosive device, comprises a double-walled cage (10) whose outer wall is constituted by a helix of wire (4) formed at regular intervals with notches (5) which extend over a fraction of the wire thickness and whose inner wall is a continuous wall (2) bounding a chamber adapted to receive an explosive charge, the outer and inner walls enclosing between them a plurality of shrapnel forming elements (3), e.g. an intermediate layer of steel balls which may be partially received in the gaps between turns of the wire (4]. <IMAGE> |
