摘要： A safety device for insertion into a pipeline (K) in which fluid circulates in an upstream (X−) and a downstream (X+) direction, comprises a tube (1) that provides the fluid with a central circulatory passage (CC) regulated by a central valve (3) that closes in the event of an excessive flow of this fluid. There is an annular valve closure member (4) which is elastically malleable, mounted to the external periphery of the tube (1), and provides the fluid with a peripheral circulatory passage which it selectively obstructs by subjecting a radial expansion in the event of an excessive flow of fluid.
