It is also sealed at its tip and executed with a number of openings distributed over an area between the tip and the connection. The external surface of the tube is covered with a coating of titanium of sufficient thinness for the tube to retain its soft characteristics. The arrangement also comprises an attachment device (3) so arranged, after insertion of the tube and after withdrawal of the aforementioned rigid body, as to be applied between the ends of the tube in order to produce a rigid connection between same.</p> |
