Abstract
The disclosure relates to a safety device to be inserted in a pipe through which a fluid flows from an upstream side to a downstream side, this device comprising a tube offering the fluid a central flow path controlled by a central valve which closes in the event of excessive flow of this fluid, an elastically deformable annular shutter mounted on the external periphery of the tube, and retention clamps. According to the disclosure, each of the clamps has a tied end fastened to the periphery of the tube upstream of the annular shutter and can adopt, under the effect of a radial compression, a folded configuration in which its free end is turned towards this annular shutter.
