Abstract
A system for connecting a tube (10) to a flexible hose (14) having an endpiece (12). One of the two parts constituted by the tube and the endpiece is suitable for fitting in the other of said two parts in a coupling situation, in which first and second locking means (26, 30) belonging respectively to the endpiece and to the tube co-operate for locking the connection. The endpiece has first and second rings (16, 18) disposed one after the other on a first of the inside and outside faces (15A) of the hose (14), and a tubular body (22) which is placed on the second of said faces (15B) . A sealing gap (20) is organized between the rings (16 and 18), and the gasket for sealing the connection is formed by a swelling (24) of hose material occupying said gap.
