1. A rod coupler comprising:
a first clamping jaw, a second clamping jaw, and locking means for locking said clamping jaws against one another, wherein each clamping jaw comprises an outside surface and a clamping surface, wherein each clamping surface provides at least two straight grooves, each groove running laterally from a different part of the outside surface extending into the rod coupler, a longitudinal axis of a first groove and of a second groove of said at least two grooves on one clamping surface include an angle (α) that is equal to or less than 160 degrees, in that said grooves are positioned on the clamping surfaces such that, when the clamping jaws face one another with their clamping surfaces in locking position, at least the first and the second groove of the at least two grooves of the first clamping jaw face each a groove of the second clamping jaw, wherein opposing grooves form an aperture, wherein each of the at least two apertures extends laterally from the outside surface of said clamping jaws into the rod coupler and is adapted for receiving a rod when the locking means is released, and wherein in that the clamping jaws are locked by the locking means for clamping the rods received in said apertures. |
