A flat groove 11 having a circumferential surface is provided, a compound 12 is put into this flat groove 11, and a curved substrate 14 having several teeth 13 protruding from above is inserted so as to cover the opening of the flat groove 11. Temporarily lock it. The curved substrate 14 has the gripping groove 10
Each tooth 13 has a curved surface with approximately the same curvature as the inner circumferential surface of
A large number of through holes 15 are bored between the holes.

い。 In this proposed example, two electric wires 16, 16 are inserted into the electric wire gripping groove 10, and compressed from the outer periphery of the sleeve body 9 using a compressor (not shown). As a result of this compression, each curved substrate 1 is
4 sinks into and abuts the inner bottom of each flat groove 11, and instead, the compound 12 reaches the surface of each curved substrate 14 through each through hole 15 and closes the opening of each flat groove 11. Further, each tooth 13 corresponds to the coating layer 16 of each electric wire 16.
a and reaches inside the core wire 16b. Therefore, since the compound 12 is interposed between the surface of the curved substrate 14 at the root of each tooth 13 and the outer periphery of the coating layer 16a of the electric wire 16, no gap is created between them.

When the wire is compressed into the wire gripping groove without being coated, a watertight packing material is interposed between the inner periphery of the wire gripping groove around the root of the tooth and the outer periphery of the coating layer of the wire, and this adheres to both. , Rainwater does not enter the wire sheathing from the outer periphery of these teeth. Therefore, it is extremely convenient to connect the wires, and there is no fear that rainwater may enter from the wire connection point and corrode the core wires.
