A portable anchor for use on a roof ( 26 ), the anchor comprising a force distribution member ( 12 ) and connection means ( 13 ) for receiving a load support line ( 28 ) wherein the connection means is positioned around the junction between the attachment member and the force distribution member ( 12 ). The attachment member ( 11 ) is preferably an elongate arrangement with a gap between a first side structure and a second side structure in the form of a clamping arrangement. The gap is dimensioned to receive an edge ( 25 ) of the roof and preferably has a stop member ( 15 ) positionable against an edge of the roof cladding. The force distribution member ( 12 ) is preferably dimensioned and configured to mate with corrugations ( 27 ) or other indentations in the roof to resist lateral displacement. The connection means ( 13 ) is positioned towards the junction of the arm and the longate member to resist the tendency for lateral rotation and displacement of the roof anchor as a harnessed worker moves laterally on the roof. The clamping means is preferably formed from two clamping arrangements ( 16, 17 ) such as cammed catches or threaded bolts.
