ABSTRACT:
There is described a three dimensional clamp for holding a plurality of rod-like elements in various relative positions and angles. The clamp body has two opposed clamping sections aligned along a longitudinal axis and joined by an obliquely extending intermediate section or strip. The two opposed clamping sections have respective tongues extending along opposite sides of the intermediate strip but normally slightly spaced from the strip so that a clamping screw passing through both tongues and the intermediate strip draws the tongues toward each other and toward the strip, thereby reducing or warping the dimensions of the bore or hole in which the respective rod-like elements are inserted. In one embodiment the hole for one of the elements is fitted with a thimble rotatable in the hole which actually receives the element. When the clamping screw is tightened, the rod-like elements are gripped, one of them being gripped by the thimble. In an embodiment which does not incorporate a thimble the rod-like elements at each clamping section are gripped in a bore or hole of the section.
