摘要

The coupling plate (5), having a slot (3) at the bottom for a safety strap (4) with a snap hook, has a round hole (6) in the middle with a top slot (7) allowing it to pass over and fit behind a nut (2) on the projecting threaded end of an anchor peg fixed in a hole in a wall or rock face. A spring-loaded catch (8) pivoted to the plate's front surface prevents any spontaneous release.
