Fitted coupling device, formed by two components, for connection to a flexible tube, having a female component and a male component on which said flexible tube is attached by thermal contraction of an external ring. The coupling device has an elastomer O-ring which is gradually compressed between two facing surfaces, one of which is essentially cylindrical and the other of which is a small-angle cone. The compression takes place during an axial manoeuver causing the rolling without sliding of said O-ring, which executes one or more complete turns on itself.
