Abstract

A joint element (4), wider at both ends, is attached to the end (51) of a tube (5) and inserted into the end (71) of a cannula (7), widening the cannula (7) slightly with its outer rim. A clamping ring (1), fitted with several axial positioned clamping elements around one of its edges, is attached to the cannula (7) enveloping the joint area and gripping with its claws around a distancing ring (2) acting on a collar (62) located at a reinforcing element (6), also enveloping the joint area, creating a perfectly sealed connection.
