Abstract
A chimney flue cleaning tool having a plurality of pole segments, a cleaning device, and a quick-connect pushbutton coupling device designed to transmit large amounts of torque via interengaging torque-transmitting structures on both of the male and female parts of the coupling that work to transmit the torque between the two parts while freeing the pushbutton from having to resist any substantial amount of torque. In one embodiment, the chimney flue cleaning tool has a coupling device with a groove and a tongue for transmitting a significant amount of torque along the longitudinal axis of the tool.
