Abstract
A sleeve (8) is introduced inside the tube (3) from the face (1a) of the tube plate, with which the tube (3) is flush, through the entire length of the tube plate (1). The tube (3) and the sleeve (8) are joined together in two zones (15, 16) by means of a binder which ensures a bond of high mechanical strength. An axial pull is exerted on the sleeve (8) from the face (1a) of the tube plate (1). The device is capable of pulling on the sleeve which operates either continuously or in steps.
