A bottom anchor assembly ( 10 ) for a substantially vertically-oriented elongate safety line ( 70 ) comprises safety line gripping means ( 20 ), safety line tensioning means ( 80 ) and a bracket ( 50 ). The gripping means ( 20 ) includes a manually adjustable clamp ( 20 ) and the tensioning means ( 80 ) includes a hollow shaft ( 40 ) through which the safety line ( 70 ) passes. The hollow shaft ( 40 ) is externally screw-threaded and carries the load-setting means ( 80 ) on its screw-threaded portion ( 41 ). The load-setting means ( 80 ) is adapted to bear against the underside of the bracket ( 50 ) for adjusting the safety line tension to a predetermined value.
