In order to improve the mechanical stability of a multi-core flexible electrical lead which is subject to frequently alternating stresses, the dummy cores (3) and/or the jacket (4) as well as the hose layer (8) fitted to each core (2) form a flexible framework in which the cores are arranged such that they can slide with the aid of a separating means (7). The dummy cores (3) the hose layer (8) and the inner jacket (4) are connected to one another by virtue of their materials by bonding or cross-linking. <IMAGE>
