To hold and carry out working operations with a tool at a considerable height above ground level, such as in washing windows and glass surfaces, a holding device is formed of a plurality of coupled rod sections forming an elongated rod with the tool positioned on one end of the rod, a holding ring is located adjacent each of the opposite ends of the rod and support members are spaced axially along the rod between the holding rings. Wire ropes extend between the holding ring and the support members and are tensioned to increase the stability of the device.
