According to the invention, the cable routing members (1, 2) are adapted to be assembled together end-to-end in order to form a cable path. According to the invention, each cable routing member (1, 2) includes at the longitudinal ends thereof either at least one longitudinally protruding lug (9) or at least one cavity (11) formed longitudinally, wherein the lug (9) protruding from a first member (1) can be tightly inserted into a cavity (11) homologous to the above one and formed in a second cable routing member (2) adjacent to the previous one, and wherein the cavity (11) formed longitudinally in a first member (1) can tightly receive a lug (9) homologous to the above one included in another cable routing member (2) adjacent to the previous one, the lug (9) and the cavity (11) being provided at identical locations from one cable routing member to another so that said members can be assembled in an aligned manner when the lug (9) is inserted into the cavity (11).
