Abstract
In a linking device (1) between strands (6) of a cable (3) and a contact element (4) comprising a hollow intermediate tube (9) provided with a channel, the tube has a first aperture (11) used for the insertion of one end (2) of the cable into the channel and a second aperture (17) to cooperate with the contact element. The tube is a solid part like the contact element. It is made of a material having a coefficient of expansion similar to that of the strands. This tube enables connexion between strands with a coefficient of expansion different from that of the contact element with which they have to be connected.
