ABSTRACT:
A principal guide-plate (12a) is bent adjacent a first edge (13a) to define a retention groove (9) extending along an axis (y,y'). A secondary guide-plate (12b) is mounted parallel to the principal guide-plate with a first edge (13b) disposed parallel to and spaced from the principal guide plate first edge. A lever (16) is pivotally mounted (21) between the guide plates. The lever defines a cam surface (26) and a locking surface (25) for engaging a safety line (6) disposed in the retention groove. The lever has an aperture (23) at a second end for receiving a safety catch (5). The guide plates define a lower surface (17a, 17b) with a smaller radius (R1) and an upper surface (18a, 18b) with a larger radius (R2). A radial stop surface (20a, 20b) extends between the upper and lower arcuate surfaces to engage the safety-catch and prevent the lever from pivoting from a closed position (FIG. 10) in which the locking surface engages the safety line toward an intermediate position (FIG. 9) and an open position (FIG. 8) in which the safety line can be released from the mechanism.
