Abstract: A connector for attachment to a wire includes a body that is made of electrically insulating material and defines a passage for receiving an end segment of the wire. The electrically insulating body has a first attachment structure at a first side region and a second attachment structure at a second side region. The first and second attachment structures are at least partially complementary. An electrically conductive interconnection element has first and second edge portions exposed at the first and second side regions respectively and has a medial portion exposed in the passage. The medial portion of the interconnection element is shaped and configured to enter electrically conductive contact with an end segment of a wire that is inserted in the passage and the first and second portions of the interconnection element are at least partially complementary.
