ることができる。<Effects of the invention> As is already clear from the above explanation, the invention has the following effects:
In the sleeve for connecting electric wires, the outer periphery of the part where the metal sleeve is deformed by pressure is covered with a covering sleeve, and covering tubes for maintaining insulation are attached to the outside of both ends of the covering sleeve using heat-shrinkable resin material. Because it is formed to protrude, the outer periphery of the wire that is deformed under pressure by the pressure tool is protected by the covering sleeve, and it will not be destroyed by the pressure tool and there is no risk of electrical leakage. It is safe, and the heat-shrinkable tube can be made into a thin film that does not impede the flexibility of the wire, making it easy to heat-shrink the tube and make it adhere tightly to the wire, ensuring watertightness at the wire connection. Therefore, it has the advantage that it can be used as a connection sleeve without the risk of electrical leakage even in humid areas.
In particular, since an adhesive layer is formed on the inner surface of the sheathing tube using a heat-melting resin or adhesive, there is no risk of water droplets entering the connection sleeve from the wire sheathing, allowing safe wire connection. Can be used as a sleeve.
