Abstract: A cleaning tool comprising an extendable pole of two or more telescoping tubular members of a non-circular cross-section and having locking-clamping devices with the same form of noncircular cross-section. The telescoping tubular members are connected together through a clamping device, wherein one open end of the clamping device comprises an internal surface matching an external surface of a thicker tubular member and the second end of the clamping device comprises an internal surface and further comprises a notch extending through the length of the second end of the clamping device, and a lever mechanism, wherein the second end of the clamping device is arranged for diameter reduction upon performing a clamping action with said lever. The free end of the thinnest tubular member comprises means for attaching a cleaning tool.
