Abstract: An avalanche probe for locating and rescuing people buried by an avalanche is collapsible, having several probe segments which allow the probe to be folded to a compact unit that can be quickly and easily assembled for use. A connecting cord passes through the probe segments and fastens to a probe tip. Applying tension to the cord draws the segments into alignment. A clamping mechanism maintains the tension on the cord in such a manner that the probe segments are fixedly and securely held against one another. The clamping mechanism provides two interpenetrating elements, an outer element and an inner element having a passage therethrough. At least one clamping element passes into the central passage and is forcibly engaged with the cord as the interpenetration of the elements increases.
