Cord locking and blocking device for e.g. mountaineering, has opening arm rotated between two positions by spring wire, where arm has operating opening for transversal passage of operating snap hook in free end zone of arm

摘要

The device has a crossing passage (7, 8) defined by main braches (2) and lateral branches (5, 6). An operating arm (11) with a free end zone (11a) and an end (11b) is articulated on the branches (2), where the arm rotates between a position close to an edge (2c) of the branch and a rotated position spaced from the edge by a spring wire (12). The arm has an operating opening (11c) for a transversal passage of an operating snap hook in a free end zone.
