An expander 17 having lugs 18 which fit into the slots is forced towards the end 21 after the insert has been inserted in a body 20, to expand the fingers. A plate may be held on the body 20 by the head 23, which may have projections on its under face to dig into the adjacent face of the body, or a washer may be carried by the head to engage the plate.
