An apparatus for connecting an implant with a rod comprises a body, a collet, an annular ring member, a washer, and a nut. The body defines a first channel to receive the rod and a second channel extending through the body. The collet is positionable in the second channel and defines an aperture for receipt of the implant. The ring member includes a gap and defines an aperture for receipt of the collet. The washer is positionable adjacent the second channel and is configured to translate along the body to allow pivoting of the collet relative to the body. The nut is operable to connect with the collet to move the collet within the second channel. Movement of the collet is operable to expand the ring member and contract the collet around the implant to secure the implant at a desired position.
