In another variant, the front part of the protective sleeve is superimposed with the rear part of the connecting sleeve in the first securing area.

Preferably, the front part of the protective sleeve and the rear part of the connecting sleeve each comprise a single textile layer.

Preferably, the front part of the protective sleeve is disposed inside the connecting sleeve, in contact with the inner face of the rear part of the connecting sleeve.

In a variant, the first electrically conductive securing area comprises three or four textile layers secured in their thicknesses in an electrically conductive manner, including at least two textile layers of the protective textile sleeve, and at least one textile layer of the connecting sleeve.

Preferably, the outer portion of the rear part of the connecting sleeve is not secured in its thickness, especially in an electrically conductive manner, to the front part of the protective sleeve, that is to say to the inner and/or outer portion of the front part of the protective sleeve, and/or to the inner portion of the rear part of the connecting sleeve. In particular, the outer portion of the connecting sleeve does not comprise any welding.

In one embodiment, the three secured textile layers comprise the outer and inner portions of the front part of the protective sleeve and the inner portion of the rear part of the connecting sleeve.

In one embodiment, the four secured textile layers comprise the outer and inner portions of the front part of the protective sleeve and the inner and outer portions of the rear part of the connecting sleeve.
