The baseboard (1) has a cross-section which consists of a contour (4) and another contour (5) lying opposite to the former contour. The former contour is rotated in an end area (2) of the cross section around 180 degree around a symmetry point corresponding to the latter contour in another end area (3). The two contours in the former end area are curved or angled on the same side. An independent claim is included for a connector with a connection area. |
