ABSTRACT:
The invention relates to a connecting element for connecting a screw in the spine with a stabilizing rod, the connecting element being easily and quickly securable. The connecting element includes a receiving section which receives the stabilizing rod and which is part of a tension member having a threaded shank. A sleeve is arranged around the receiving section and can slide parallel to the shank axis. In the wall of the sleeve, two openings are present for positioning the rod. The connecting element further includes a nut which can be screwed onto the shank in order to fix the head of the pedicle screw at the sleeve. This connecting element has the advantage that by a single securing process (i.e., the tightening of the nut) the rod can be fixed in the receptacle of the tension member and the connecting element can be secured at the screw head. Preferably, the receptacle for the rod and the recesses of the sleeve are formed so that an opening is formed which extends transversely through the sleeve and the tension member, with the rod being fixable in that opening by tightening the nut.
