Self-locking device without the flange and without welding, to smooth tube, for the connection of a flexible hose

摘要

The flexible pipe connecting sleeve (140) has external end flanges (141,142) and two shells (150,160). These each have an interior edge (151,161) covering the end flanges of the flexible connector. The shells also have a peripheral cavity (153) open towards the tube in which an anchor ring (170) is located. The anchor ring has claws (171',171'') which contact the tube (110,111) and lock the shells.
