This arrangement makes it possible to have a rounded clear junction between the connecting and protective textile sleeves, thus avoiding any risk of snagging on the path of the shielding device. The tear strength of the junction thus formed is also improved compared to a junction according to which the annular front part of the protective sleeve would be placed inside the unfolded annular rear part of the connecting sleeve.

Especially, the front part of the protective sleeve comprises a single textile layer in the first securing area and the rear part of the connecting sleeve comprises two superimposed textile layers, especially in the first securing area.

Preferably, the rear part of the connecting sleeve is folded inside its interior volume.

It is understood by folded on itself that the rear part of the connecting sleeve comprises a folded portion facing the connecting sleeve, directly against the connecting sleeve or around (that is to say by sandwiching) one or several elements, for example around at least a portion of the protective sleeve.

In a variant, the rear part of the connecting sleeve comprises an inner portion at least partly secured to the protective sleeve, especially to the front part thereof, and an outer portion, superimposed on the inner portion and in the extension of the inner portion.

The inner and outer portions of the rear part of the connecting sleeve each comprise opposite inner and outer faces, the outer faces being oriented towards the outside of the interior volume of the connecting sleeve.

The front part of the protective sleeve comprises opposite inner and outer faces, the inner face being oriented facing the interior volume of the protective sleeve.
