Claim:
1. A lifting plug for a high explosive projectile capable of forming a vent by a thermal fuse, the lifting plug being mounted to a front part of a shell of the projectile by being screwed thereto with a fuze being removed from the front part, the lifting plug comprising: (a) a plug body; (b) a handle provided on the plug body; (c) a window combined with the plug body by a bolt fastened to respective locking holes of the plug body and the window; and (d) a thermal fuse charged under the bolt such that when the thermal fuse is ignited, the window can be removed from the plug body by explosive power generated by the thermal fuse, thereby forming a vent in the lifting plug and preventing ignition of a supplementary charge and a main charge of the projectile, and thus preventing an explosion of the projectile.
