<p>A system for securing a life-line (20) around the outside o a structure, e.g., the wheelhouse of a boat, includes attachment devices for the life-line at intermediate positions therealong (particularly at corner parts of said structure) which allow a hook of a safety line attached for sliding movement to the life-line, to pass those attachment points. In one embodiment each attachment device comprises a recessed wheel (10) and a slipper member (14) located to embrace tip portions of the wheel projections (11) to be held thereby while allowing rotation of the relative to the slipper member. In this way the slipper member guides the line (20) in an arcuate path around a peripheral part of the wheelhouse to allow a hook (31) engaged for sliding movement along the life-line to traverse the attachment point by engaging in a recess (12) in the wheel which then rotates relative to the slipper member (14) to pass the hook (31) through the attachment device.</p> |
