An anti-flooding safety device for a user apparatus comprises: - a first connection body (20) defining a first duct, the first duct having an inlet (11, 23a) and an outlet (23b), the inlet of the first duct (11, 23a) being provided for connection to a supply point of a mains supply; - an inner flexible hose (17) and an outer flexible hose (16) impermeable to water, wherein the inner hose (16) has a proximal end, which is sealingly fixed in a position corresponding to the outlet (23b) of the first duct, and a distal end for connection to the user apparatus, and wherein the inner hose (17) extends longitudinally within the outer hose (16) so that between at least part of the two hoses (16, 17) a gap (18) is defined designed to convey to the user apparatus and/or to withhold inside it any possible leaking water; and - a valve arrangement (30, 72, 80, 83) on the first connection body (20), which can be switched from a position of opening of the first duct to a position of closing of the first duct following upon detection of a leakage of water. The axis of the inlet (11, 23a) extends in a direction transverse to the axis (B) of the outlet (23b). |
