<p>PURPOSE:To use a wire protective cover to be connected in a desired length without using a coupling tube or the like at all, or without adjusting the length by cutting it by composing it of bellows type cylindrical bodies of a large and a small diameters combined with each other. CONSTITUTION:A wire protective cover is formed of a small-diameter and a large-diameter cylindrical bodies 1a, 1b connected to each other. Each cylindrical body 1a, 1b is of a bellows form provided with protruded parts 2 and recessed parts 3 respectively to be bent along length. The cylindrical body lb acts as a joint to have the cylindrical body 1a engaged inside, and the cylindrical body 1a is formed long, while the cylindrical body lb is short. The cylindrical body 1a is separated along the length to be opened at a lower end. This separation end 4 is provided in a wavy form along the length, and guide protrusions 5, 6 for introducing a wire are provided along the separation end 4. The cylindrical body 1b is also separated along the length, and guide protrusions 5', 6' are provided for introducing the wire through an interval for holding the protrusions 5, 6. The inner diameter of the cylindrical body 1b is formed in such a size that the outer diameter of the cylindrical body 1a can be inserted and engaged.</p> |
