ABSTRACT:
A corrugated tube with a longitudinal slit is loaded with electrical wires and the slit is locked. This process is effected using one device and in a single step. The corrugated tube is provided on its outer surface with circular peaks and troughs alternating along the axial direction. The portions facing one another across the slit are provided with convex and concave shapes along the circumference of the tube forming female and male locking portions. The male locking portion is inserted under the female locking portion, so as to lock the slit. An automatic locking device has a tubular guiding unit having a slanted tube part, and a tubular locking unit. The wires pass through the slanted tube part and the tubular locking unit. The tubular guiding unit is inserted into the slit, and 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.
