You'll need a 1/16 pin punch and a small tack hammer.
With the tensioner's filament pointed upwards you should be able to find the pivot point on the left side. The word "PUSH" is embossed around the hole. Using your punch pin you will push the pin out of the pivot point, use the tack hammer if this proves difficult. Hold onto the pin! You'll need that in a moment.
Once the pin is removed the tensioner will come free of it's hinge, unlace it from the other anchor points and you'll be able to install it's replacement. Orient the replacement on the hinge in the same manner as the original. Now you'll just need to slid the pin back into place, only this time it will be coming in from the other side of the tensioner on the right.

The Techno III Tensioners can be found on all "Wire," and "Drako" cycling shoes as well as on the "Astro" (formerly the Nitro) motorcycle boot.
