The clamp is u-shaped (1) with bores at its outer ends (5, 6) holding clamping elements (12), each provided with three spikes (14) at the front. A first element comprises a movable spike holding plate (15) located close to the arm of the device (1), while the second element is attached to the front of a spindle (10) with a ball thread acting in combination with two spheres positioned opposite each other in recesses at the inner surface of a bearing and kept in a locked position by a catch (35).
