Abstract
A corrugated tube has alternating ridge and trough shapes, viewed in longitudinal cross-section. The tube also has a slit along its longitudinal direction, thereby forming first and second portions flanking the slit. The first and second zones comprise a first and a second end portion of the ridge shapes, respectively. The first end portion forms a convex portion, while the second end portion forms a sequential convex and concave portion. Each portion extends from the slit side around the opposing circumferential directions, thereby forming female and male locking portions, respectively. When the male locking portions are inserted under the female locking portions, the convex portion of the first zone and the sequential convex and concave portion of the second zone are stacked and the slit is firmly locked.
