A connection device includes a connector provided with wire insertion holes receiving end portions of electrical wires and terminal fittings connected to the end portions. The electrical wires include a lead wire and a dummy wire. One end of the lead wire is inserted in the wire insertion holes while another end of the lead wire is connected to another connector. One end and another end of the dummy wire are inserted in empty ones of the wire insertion holes. A protective tube, which is shorter than the lead wire, is provided between the connector and the other connector, so as to extend over an entire length of the lead wire except opposite end portions of the lead wire and so as to cover the lead wire and the dummy wire. A U-shaped curved end portion of the dummy wire is exposed from an end portion of the protective tube.
