ABSTRACT:
A clamping device is formed of nestable body members pivotally hinged together, forming an inner space between them, housing and slidably supporting an elongated body such as a cable, bar, tube or the like in pivotally closed position, the large member having side walls one of which is elongated and the other shortened and forming an open space for receiving said elongated body and for mounting of said clamping device about any point thereon, one body member pivotally supporting a clamping means comprising an inner portion cam-shaped and pivotally bearing against and gripping said elongated body, an outwardly extending trigger arm for actuation by a chain worn about or attached as a safety device to the waist of a climber, ascending or descending a ladder or the like. Ascent of the climber allows him to draw the clamping device slidingly upon the elongated body as he ascends or descends the ladder, pivotally pulling the cam element out of gripping engagement of the elongated body. A reverse pull causes the cam to grip and clamp the device to the elongated body.
