    Abstract: An adjustable length ski pole includes two telescopically fitted together ski pole halves, and a clamp disposed about the joint between the two pole halves. The clamp includes a resilient tubular member having an annular sidewall which defines a cylindrical bore, where the sidewall is formed with a longitudinally extending gap to allow the tubular member to be selectively biased to reduce the gap width and thus the diameter of the bore, or to enlarge the gap width and thus the diameter of the bore. The gap defines first and second opposing sidewall edges having coaxial first and second openings respectively.
