Apparatuses are disclosed for use in orthopedic surgery, for example for procedures in which a support member is connected to the spine. A connector member for connecting to an orthopedic implant and a support member is provided. A sleeve fits around the implant, and a locking member or mechanism connects to the sleeve. Locking causes a part of the sleeve to press the support against the connector, and causes a part of the sleeve to compress around the implant, so that the implant and support are substantially inhibited or prevented from moving with respect to each other.
