An electrical connector element of the banana plug type which includes an elongate metal body having a core and a base. The base is connected to a lead or wire, and the core has a nose thereon at the end thereof remote from the base. The base and the nose form shoulders at the regions thereof adjacent the core. The surface of the core between the shoulders is a surface of revolution about the axis of the core. The surface of revolution is relatively close to the axis at regions near the shoulders and relatively far from the axis at regions far from the shoulders. The connector element further includes an electrically conductive spring, such as a barrel spring, mounted coaxially on the core between the shoulders. The spring has a central region located outwardly of the regions of the surface of revolution that are far from the axis.
