Claim:
A cross clamping device comprising: a base plate, which has a first and a second leg and a clamping piece which connects the two legs with each other, a first clamp, which by means of a first screw is screwed onto the first leg, and a second clamp, the second clamp being separate and distinct from the first clamp, which second clamp by means of a second screw is screwed onto the second leg, wherein the base plate and the two clamps are so formed that between the first and the second clamp a first bar, and between the two clamps and the clamping piece of the base plate a second bar, which is rotated by 90° in relation to the first bar, are able to be clamped, wherein the first and the second screw each have a head, which is at least partially conical shaped, so that by tightening of the first and of the second screw the first and the second clamps are pressed by the slanting conical surface against the first bar and the two bars are clamped.
