Abstract

The rod coupler according to the present invention comprises two clamping jaws and locking means for locking said clamping jaws against one another. Each clamping jaw comprises an outside surface and a clamping surface, the latter providing at least a first and a second groove. Each groove runs laterally from a different part of the outside surface extending into the rod coupler, wherein longitudinal axis of the first groove and the second groove include an angle that is equal to or less than 160 degrees. Opposing grooves form an aperture. The apertures are adapted for receiving a rod if the locking means is released. Clamping jaws that are locked by the locking means clamp the rods received in said apertures.
