Abstract: An electrical contact device for use as part of an electrical contact unit. The device comprises a body having a central part and a pair of end parts, one of the end parts adapted to be coupled to a wire and the other end part defining an extension which is removably received within a second, tubular contact element forming another part of the electrical contact unit. A sleeve surrounds the extension and is spaced therefrom to present an annular space for receiving the tubular element. A male contact band surrounds and is coupled to the extension and a female contact band is carried within the sleeve. Both bands have electrically conductive, curved contact members which project into the annular space from opposite directions and contact the inner and outer surfaces, respectively, of the tubular element when the same is in the annular space between the extension and the sleeve.
