A corrugated tube (10) is provided on its outer surface with circular peaks (12) and troughs (13) alternating along the axial direction and has a longitudinal slit (11). The peak portions facing one another across the slit are provided with convex and concave formations sequentially in the circumferential direction starting at the slit, so as to form female (14) and male (19) locking means. An automatic locking device (30) comprises a tubular guiding unit (32) having a slanted tube part (32a, 32b), and a tubular locking unit (33). The wires (W) are passed through the slanted tube part and the tubular locking unit. A bottom part of the tubular guiding unit is inserted into the slit, whilst the corrugated tube inside the tubular locking unit. When the device and the corrugated tube are moved relative to each other in the longitudinal direction, the wires are transferred from the device into the corrugated tube and the slit is automatically locked by the locking unit. <IMAGE> |
