Abstract
On the rotor, between each blade and the member for linking with the hub, an electrical connecting cable comprises a first section of which one part is held above that one of the two blade pins which is the detachable pin whose withdrawal allows the folding of the blade by pivoting about the other blade pin forming a pivot pin, by a holding arrangement tied to this detachable pin, in the flight position of the blade. This section of cable is released from its holding arrangement before the withdrawal of the latter and of the detachable blade pin, which precedes the folding, in such a way that this section of cable deforms naturally on following the pivoting of the blade. After deployment of the blade, a part of the section of cable is again held in the holding arrangement, in the flight position of the blade.
