ABSTRACT:
A security device for detachably attaching a lanyard to a safety device. The device includes a main frame portion defining a U-shaped safety line channel for receiving a safety line, and a movable frame portion pivotally mounted to the main frame portion and carrying a cam portion for frictionally engaging the safety line. The cam portion is movable into engagement in response to a downward force from a lanyard attached to the movable frame portion. The cam portion is mounted on bushings aligned with apertures in the main frame portion and held in position by removable pin members. The pin members, in combination with the bushings provide a strong beam structure extending across the main frame portion to provide a rigid support structure for the cam portion for resisting deformation of the structure when a heavy load is applied. In addition, the pin members may be removed to allow the movable frame portion to pivot to an open position for allowing insertion and removal of the safety line to and from the security device.
