ABSTRACT:
A security device for providing a detachable and adjustable connection of a workman's safety belt lanyard to a safety line or the like. The device includes a pair of vertically spaced pivotally mounted cams having serrated cam faces directed into a vertical channel adapted to receive a safety line. The cams are joined by a link to maintain their parallel relation and are spring loaded toward a line engaging position. A pivoted eye connected to the link provides an attachment point for a lanyard. The frame of the device includes pivotally connected front and rear frame portions which may be opened to apply the device to or remove it from a safety line. A latch mechanism provides a secure locking of the frame portions in their closed line clamping position, but may be readily released to allow removal of the device from a line.
