Abstract: An extrudable flexible material profile (1), for marking electric leads, cables, hoses and other elongate objects (12). The profile comprises a center portion (4) oriented along the longitudinal axis of the profile. Locking means (3) extend in parallel with said longitudinal axis (13) at each side of the center portion (4) which by mutual coupling-up are making it possible for the profile to form a closed hollow section. The material thickness of the profile is dimensioned for flexibility in the center portion (4) and for rigidity in the lock means (3).
