Abstract: A ski pole shaft is cut into two parts and a lock mechanism is interconnected between the two parts. The lock mechanism is telescopically moveable between an open position in which a pair of shackle jaws carried by the two parts are spaced axially apart, and a close position in which the two jaws are close together. One or both of the jaws may be formed to include a cordwise extending groove in the side thereof which faces the other jaw. A security line which is normally housed within the ski pole is pulled out from the ski pole, until an abutment at its inner end meets a stop that prevents further movement. The security line is wrapped about ski equipment and a fixed support and then a portion of its free end is set within the groove and the upper and lower sections of the pole are moved telescopically together. A combination lock carried by one part of the lock mechanism is operated to lock the two sections of the ski pole together.
