  • Patent number: 11920350
    Abstract: A drainage device is provided. The drainage device includes a drainage head having at least one head portion having an internal collection space and provided with at least one through recovery passage, and an attachment sleeve at least partially deformable. The attachment sleeve can be secured to the drainage head and capable of being inserted inside the flow pipe. The drainage device further includes a compression washer attached on the attachment sleeve and a central screw. The central screw can be movable in relation to the drainage head and threadably engaged with the compression washer to obtain, under the effect of a rotation of the central screw relative to the drainage head, an axial movement of the compression washer on the side of the drainage head and an outward radial deformation of the attachment sleeve.
