An elastic tubular sleeve (8) in engagement with a tubular supporting element (9) is set to a substantially coaxial position around one of the electric cables (2a, 2b) . Subsequently, the conductors (3a, 3b) of the cables (2a, 2b) are mutually connected to obtain a splicing region between said cables. The tubular sleeve (8) in engagement with the supporting element (9) is positioned around the splicing region. By use of a suitable apparatus (100, 101, 102) previously engaged on the sleeve (8) and the supporting element (9), the supporting element (9) is drawn out of the tubular sleeve (8) so as to cause a radial elastic shrinkage of the tubular sleeve (8) capable of inducing an axial ejection thrust on the supporting element (9) itself. Counter devices (12) associated with the apparatus (100, 101, 102) counteract the axial ejection thrust so as to allow the speed at which the supporting element (9) is drawn out of the sleeve (8) itself to be controlled.

L'invention concerne un manchon tubulaire élastique (8), en prise avec un élément de support tubulaire (9), qui est installé sur une position sensiblement coaxiale autour de l'un des câbles électriques (2a, 2b). Ensuite, les conducteurs (3a, 3b) des câbles (2a, 2b) sont reliés mutuellement afin d'obtenir une région d'épissure entre lesdits câbles. Le manchon tubulaire (8,) en prise avec l'élément de support (9), est positionné autour de la région d'épissure. Grâce à l'utilisation d'un appareil approprié (100, 101, 102) engagé au préalable sur le manchon (8) et sur l'élément de support (9), l'élément de support (9) est tiré hors du manchon tubulaire (8) de sorte à provoquer un rétrécissement élastique radial du manchon tubulaire (8) capable d'induire une poussée d'éjection axiale sur l'élément de support (9) lui-même. Des contre dispositifs (12) associés à l'appareil (100, 101, 102) agissent contre la poussée d'éjection axiale de façon à permettre de réguler la vitesse à laquelle l'élément de support (9) est tiré hors du manchon (8) lui-même.
