ABSTRACT:
Safety apparatus for used by workers at height comprises a fixed safety cable (1) secured in spaced relation to a fixture (2) by supports such as (3), and a coupling device (8) by which a safety line attached to a worker's safety harness can be coupled to such cable. The coupling device comprises a rotatably mounted tube (9) having a longitudinal slot (16) and profiled ends (9'). The tube (9) is slidable along the cable (1). On abutment of a tube end (9') against an arm (5) of a support (3) the tube becomes rotated to bring the slot (16) into register with the arm (5) so that the coupling device can travel past the support (3).
