A safety line terminates in a section having a series of flexible loops 7, 7A, 7B, 7C, 7L extending from a base member 3. The end of the section attaches in use to an anchor point 31 and is retained by first loop 7 in the series being inserted through an anchor loop 5 and the remaining loops 7A, 7B, 7C, 7L; 7L being inserted through the preceding loop to form a linked sequence (fig. 3). A retaining device (such as that shown at 121) secures the final loop 7L which is releasable to allow each loop in the linked sequence to disengage from the preceding loop until the first loop 7 disengages from the anchor loop 5 and the line detaches. The intention is to employ a sufficiently long chain of loops to reduce the release force so as to allow a quick release of the safety line. Various forms of retaining device for the final loop 7L and ways of attaching the line to an anchor point are disclosed. |
