In other words, when the present invention is used as an electromagnetic wave shielding material, the sleeve body 1 is used, such as copper, through Raw materials (not shown) of iron, aluminum, tin, etc., or these (installed) on the surface, can also be simply used as electromagnetic wave shielding materials, the present invention includes these owners . (Effects of the Invention) The present invention is constituted as described above, and is loaded and unloaded from the paper by using the above-mentioned nesting system. It is applicable to China National Standard (CNS) A4 specification (210X297 mm) -14-401734 A7 _B7 V. Invention Explanation (12) If there is a connector end for stopping the terminal of the connector element, the terminal of the sleeve body can be set freely as the length of the covered wire, and it can also reliably prevent the joint that violates the will in the past. The opening effect of the fitting is excellent. The end of the joint is provided on the end edge of the sleeve body via a locking member that is detachably locked between the pitches of the joint element. Since the joint can be simply and reliably locked Therefore, compared with the previous protective cover, it has the effect of stronger engagement. In addition, the joint element is a synthetic resin material such as polyacetal resin or nylon resin, and at least the thermoplastic elastomer is blended directly with the end edge of the sleeve body. In the past, the joint band was unnecessary and the cost was lower. Of excellent results. Moreover, if the above-mentioned sleeve body is formed by being stretchable and retractable, it will be deformed in accordance with the shape or size of the article to be protected, and therefore it has the effect of being able to be maintained in a tensioned and fixed state. Printed by the Central Working Group of the Ministry of Economic Affairs, Shellfish Consumer Cooperatives (please read the precautions on the back of this page first to write this page). If the insulation material and / or protective material such as polyurethane foam is installed in the above body, then It can also be used most appropriately as a protective cover for a water pipe in a cold zone. Compared with the previous one, it has the effect of being extremely simple and strong with the installation and disassembly of the pipe diameter and the fixing system. In this way, since the present invention can set the terminal according to the length of the protection product (commodity) to be covered, it can be used for no reason. At the same time, it can simply and firmly prevent the opening of the engaging element against the will, because of the constitution Since it is simple, it can be applied to mass production, and it can be supplied to those who need it as a low-cost product.
