The invention relates to a hand-guided power tool with a telescoping section. The hand-guided power tool is provided with a drive motor and a tool unit with a tool driven by the drive motor. A guide tube with telescoping section with external and internal tubes is provided, wherein the internal tube is longitudinally slidable within the external tube. A device for transmitting drive energy for the tool is guided through the guide tube. A clamping device secures the internal tube relative to the external tube and has a clamping member supported rotatably relative to the internal tube and connected by a thread connection to the external tube. The clamping device is provided with at least one curved clamping ring arranged about an outer circumference of the internal tube. Compression of the clamping ring in longitudinal guide tube direction effects a size reduction of a clamping ring opening. The at least one clamping ring has a first axial face supported relative to the external tube and a second axial face sup
