An auxiliary safety mechanism for a grenade to prevent detonation from shockwaves, heat, fragments, etc., the grenade including a fuse housing containing a delay detonator and explosive train. In at least one embodiment, the fuse housing includes a reversible slider element interposed between the delay detonator and the rest of the explosive train to form a barrier therebetween when the grenade is in an unarmed condition, and when the slider element is withdrawn the barrier between the delay detonator and explosive train is removed leaving the grenade in an armed condition. In another embodiment, a further safety mechanism involves connecting the two sections of the housing with a weak connection that ruptures prior to the explosive contained therein reaching the critical explosive temperature/pressure.

1. An auxiliary safety mechanism for a grenade to prevent detonation, the grenade including a fuse housing containing a delay detonator, explosive train, safety lever, spring activated striker mechanism, and a safety pin, the auxiliary safety mechanism comprising: a reversible slider element, interposed between the delay detonator and the explosive train, the reversible slider element being configured to form a barrier between the delay detonator and the explosive train when the slider element is under tension, the slider element being maintained under tension by the striker mechanism, and the safety pin being configured to restrain pivoting of both the safety lever and striker mechanism. 2. An auxiliary safety mechanism as claimed in claim 1, further comprising: at least one stop device to engage the terminal end of the slider element to limit extension of the slider element. 3. An auxiliary safety mechanism as claimed in claim 1, wherein the safety pin is configured to restrain the pivoting of both the safety lever and the striker mechanism. 4. An auxiliary safety mechanism as claimed in claim 1, wherein the slider element is held under tension by an end of the striker mechanism. 5. A grenade comprising a fuse housing and auxiliary safety mechanism as claimed in claim 1. 6. A grenade as claimed in claim 5, wherein the fuse housing comprises two interfacing shell sections, wherein an interface formed by the two interfacing shell sections is configured to be sufficiently strong to maintain integrity of the housing and to withstand bursting under ordinary handling and limited pressure, and wherein the interface is configured to burst into separate the two interfacing shell sections when the shell is penetrated or heated to a temperature just below a temperature required to activate any explosive contained in the housing. 7. An auxiliary safety mechanism for a grenade including a fuse housing, a bore containing in series a delay detonator and explosive train, a safety lever, a spring activated striker mechanism, and a safety pin, the auxiliary safety mechanism comprising: a slider element, including a relay charge at one end and a terminal end in contact with at least one tension device, the at least one tension device being configured to extend and retract the slider element to provide a barrier between the delay detonator and explosive train when the at least one tension device is compressed, and being configured to align the relay charge with the delay detonator and explosive train when the at least one tension device is released, the safety pin maintaining the spring and striker mechanism under tension and the slider element being held under tension by at least part of the striker mechanism. 8. An auxiliary safety mechanism according to claim 7, wherein the at least one tension device includes a spring. 9. An auxiliary safety mechanism as claimed in claim 8, where the spring is a coil spring. 10. An auxiliary safety mechanism as claimed in claim 7, wherein the slider element is disposed parallel and above the at least one tension device and a terminal end of the slider element engages one end of the at least one tension device. 11. A grenade comprising a fuse housing and auxiliary safety mechanism as claimed in claim 7. 12. A method of constructing a grenade to withstand shock waves without detonating, comprising: introducing an auxiliary safety mechanism into the grenade to prevent detonation, the grenade including a fuse housing containing a delay detonator, explosive train, safety lever, spring activated striker mechanism, and a safety pin, the auxiliary safety mechanism including a reversible slider element, interposed between the delay detonator and the explosive train, the reversible slider element being configured to form a barrier between the delay detonator and the explosive train when the slider element is under tension, the slider element being maintained under tension by the striker mechanism, and the safety pin being configured to restrain pivoting of both the safety lever and striker mechanism. 13. A method of storing grenades safely without fear of detonation during storage, comprising: storing said grenades, each equipped with auxiliary safety mechanisms, each grenade including a fuse housing containing a delay detonator, explosive train, safety lever, spring activated striker mechanism, and a safety pin, and each auxiliary safety mechanism including a reversible slider element, interposed between the delay detonator and the explosive train, the reversible slider element being configured to form a barrier between the delay detonator and the explosive train when the slider element is under tension, the slider element being maintained under tension by the striker mechanism, and the safety pin being configured to restrain pivoting of both the safety lever and striker mechanism.
