Abstract:
A clamp having at least one clamping assembly comprising a base plate and a pair of tension elements, the base plate including a pair of oblong holes which converge towards a central line, each of the two tension elements being at least partially curved at its peripheral face, the peripheral face being made of a skidproof non-slip material, a respective tension element being mounted in a respective one of the two oblong holes and positioned such that its axis is substantially perpendicular to the base plate, the tension elements furthermore being arranged, such that the curved peripheral faces thereof are exactly opposed to each other, and the tension elements being slidable in their respective oblong holes by means of a slider, and wherein they are rotatably seated by means of ball bearings, each of the tension elements having a longitudinal axis about which to freely rotate, wherein a distance between both opposing peripheral faces of the tension elements can be varied by sliding thereof in the oblong holes, and the distance can also be varied by rotation of the tension elements via the ball bearings from a first position to a second position, each of the tension elements being conically shaped in a direction of the longitudinal axis associated therewith.
