A connector for providing semi-permanent connection between a bus bar and a connector contact is formed by ovelapping a bus bar tab with at least one contact tail of the connector contact and gripping the overlapped bus bar tab and the contact tail with a spring clip. In this manner, the spring clip produces the pressure required to establish adequate contact between the bus bar tab and contact tail. According to another feature, the junction including the bus bar tab, the contact tail and the spring clip are isolated by covering them with an electrically insulating sleeve, this sleeve also serving to retain the spring clip in position.
