The anchor is preferably a wedge anchor and the invention extends to a method of anchoring the rock anchor in a hole by means of a rod which is passed up into the elongated element from the mouth of the hole to tension the elongated element and activate the wedge anchor to lock the anchor against the side of the hole to hold the elongated element in the hole under tension.
