A device for clamping a fixation element which may allow for repositioning of the fixation element. The device may include a body comprising a front end, a rear end, an outer surface, a through bore extending between the front end and the rear end, a structure enabling deformation of at least a portion of the body, and a thread along at least a portion of the outer surface. The body may be tapered and the through bore may be sized and configured to receive a fixation element. The clamping device may also comprise a receiving member having a tapered bore with an inner thread sized and configured to receive the thread of the body. Insertion of the body into the tapered bore of the receiving member may result in at least a portion of the body being deformed. As the body is inserted into the tapered bore, the dimension of the through bore may decrease so that the body firmly engages the fixation element. Such a construction may allow for the body to be loosened from the tapered bore, the fixation element, body or receiving member to be repositioned, and the body re-tightened into the tapered bore.
