An assembly having a male and female plug. The female plug has an elongate cavity extending along a longitudinal axis and having in the cavity signal conducting elements. The male plug has an outer surface positioned partly within the cavity with signal conducting elements provided on the outer surface, and clicking elements. The female plug has clicking elements that click together with the clicking elements of the male plug when it is introduced into the female plug along the longitudinal axis. The signal conducting elements engage one another when the clicking elements of the male and female plugs are clicked together. The clicking elements of the female plug are positioned, in a cross section in a plane perpendicular to the longitudinal axis, symmetrically relative to a center point, in the plane, between positions of the clicking elements.
