Abstract: Disclosed is a terminal binding post for selectively mounting a wire, a fork connector and a banana plug which includes: an electrically insulated housing; an electrically conducting contact member received within a cavity of the housing; and a clamping member having an exterior clamping surface and an interior clamping surface defined in a clamping slot for receiving a tab of the contact member. The clamping member and contact member define separate wire receiving and fork connector receiving spaces. An aperture and a slot are defined in the housing which are sized and dimensioned for respectively receiving a wire and a fork connector. The clamping member is moveable in the cavity with respect to the contact member between a wire engaged position in which the clamping member securely engages the wire to the first tab of the contact and a wire disengaged spaced therefrom.
