A locking mechanism interconnects telescoping outer and inner tubes between extended and retracted lengths, such as for a trek or ski pole. A detent or pin movably extends between the outer and inner tubes to secure the tubes with respect to one another. A connector sleeve can be disposed on one tube, and movably receive the other tube therein. A button can be carried by the sleeve, and is depressable to force the pin away from the outer tube, allowing the inner tube to slide. The button can be formed on an annular band that deforms when the button is depressed, and the resiliently returns to its initial shape when released to bias the button away from the detent or pin. |
