The system includes, in addition to the sleeve (11), a tubular core (12) for keeping in a stretched condition the sleeve, adapted to receive inside it the elongate member, and a film (13) with a low coefficient of friction placed between the sleeve (11) and the core (12) to enable the core to slide relative to the sleeve. The film (13) extends at least from a first end (15) of the sleeve to a first end (17) of the core (12) opposite the first end (15) of the sleeve, makes a half-turn at the first end (17) of the core (12) and then extends inside the core as far as its second end (18) at which it makes a half-turn and then extends outside the core (12) as far as the sleeve (11) to which it is fixed externally.
