Abstract
A clamping device (1) for a walking pole for securing an inner tube (3) which can be slid into an opening of the clamping device that is secured to an outer tube (2). There is a plastic sleeve (4), on which a clamping lever (6) is hinged against the force of a spring element (10). The clamping lever (6) has a first lever arm (12) for releasing the clamping device (1) and a second lever arm (11) arranged on the other side. The second lever arm (11) has a protrusion (9) which is arranged radially to the pole axis (36) and which engages into and through a radial through-opening (19) in the plastic sleeve (4) and engages into a groove (22) of the inner tube (3) in a formfitting manner in order to axially secure the two tubes (2, 3).
