Yielding connecting device for poles at roadways, wherein the upper end of a base (8) and the lower end of a pole (9) each carry or are integrated with a mounting plate (1, 2). The mounting plates are connected with at least one pressure element (3) maintaining the mounting plates at a predetermined distance, and at least one tension element (4) bearing against the mounting plates to apply an axial prepressure to pressure element and keeping the mounting plates together. The pressure element (3) is an extended element with a narrow contact surface relatively to the total surface of the extended element, to each mounting plate, to provide a stilt effect at a relative sideward movement of the mounting plates. The connecting device is provided for, at a collision against the pole (9) with a vehicle, to have a relative sideward displacement of the mounting plates causing a disintegration of the connecting device. The tension elements (4) are arranged in recesses (5) or inner corners of the mounting plates. |
