The grenade has a mechanical maintenance structure (300) for maintaining studs (200) prior to operation of a spark-gap tube (100), so that studs are propelled at time of deformation/swelling of the structure under operation effect of pyrotechnic composition contained in the tube. The structure includes a material part that is molded on crown parts of the studs. An insert (400) is placed in a vicinity of an axial end of a molded part and includes a tapping part (416) that is used to support the tube and a projection (460) projects on the structure to avoid expansion of the molded part. |
