Elastic connection device. An elastic sleeve may be force fitted by its portion 1 which has annular striations 2, 3, 4 of decreasing diameter, into the hole in a wall, made for example of concrete. Axial ribs 12 are provided between the various annular striations so as to define leaktight partitions 13. A hose may be mounted inside the device and clamped by a collar interacting with the clamping zone 7. The hose may therefore be misaligned with respect to the orifice inside which the connection device is mounted. <IMAGE> |
