A novel security tether includes an intermediate flexible substrate, a first loop, and a second loop. The first loop is fixed to a first end of the intermediate flexible substrate and is switchable between a closed position and an open position. The first loop further includes a lock to retain the first loop in the closed position when engaged. The second loop is a fixed, closed loop that is coupled to a second end of the intermediate flexible substrate and is configured to allow the first loop to pass therethrough to create a secondary loop to encircle an anchor object. The first loop can be closed around an object to be secured, thereby securing the object to be secured to the anchor object when the lock is engaged. The security tether is conveniently portable and particularly useful for securing skis to an anchor object.
