A telescoping extension pole assembly includes an outer tube, an inner tube slidably received in the outer tube, and a locking mechanism having a slide button which is slidable parallel to the longitudinal axes of the inner and outer tubes. The locking mechanism further includes a resilient device which biases the slide button to a released position and a locking pin to a locked position for retaining the tubes in their adjusted position.
