FIELD: machine building.
SUBSTANCE: anti-flooding safety device comprises two connection bodies, a valve arrangement that includes valve member (72), retention member (83) for withholding valve member (72) in a respective opening position, and flexible inner hose (17) and flexible outer hose (16) impermeable to fluid, wherein inner hose (17) hydraulically connects two connection bodies and extends at least in part within outer hose (16) so that defined on at least area between two hoses (16, 17) is a gap (18) designed to withhold inside it any possible leaking water. Connection body (20) comprises a control chamber (30) that is at least in part delimited by movable element (80). There is control member (83) is coupled to movable element (80) so that displacement of latter will cause displacement of control member (83) towards a respective position of release, wherein valve member (72) is free to pass into its closing position.
EFFECT: gap (18) is in fluid communication with control chamber (30), to obtain a substantially closed volume therewith.
