A safety closure system for a tank comprises (a) complementary sections of a tank adapted to contain pressurized fluid, said sections having annular flanges which are subject to relative separation as the tank sections relatively separate due to said fluid pressurization, (b) said flanges respectively having oppositely facing annular surfaces which extend in relatively divergent relation away from the tank interior, and (c) clamp means assembled onto said flanges and having channel shape with webs extending in complementary relation in said divergent surfaces to engage the flanges and block said relative separation of the flanges at which time removal of the clamp means off the flanges is also blocked by said divergent surfaces.
