A clamp assembly for an external fixation system includes a first clamp member for engaging a first elongated member. The first clamp member includes a first jaw portion and a second jaw portion. The first and second jaw portions at least partially defining a laterally extending channel for receiving the first elongated member. The first and second jaw portions or members are connected by a hinge portion. The first jaw member includes a free end normally spaced apart from a free end of the second jaw a distance less than a diameter of the first elongated member. The first clamp member is elastically deformable to receive the first elongated member between the free ends of the first and second jaw members and into the laterally extending channel.
