    • 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.
