A double action expansion wedge is disclosed for attaching a collar to a T-post fence for utilization in conjunction with a bracing system for fences made from such T-posts. A hollow collar member has internal dimensions selected to slide over the posts, so that the collar can be positioned vertically between the lugs of the post at a desired location. The double action expansion cam wedge secures the collar between adjacent lugs on the post by tightly wedging the collar and post together. The double action expansion causes the top edge of the collar and the bottom edge of the collar both to be wedged against the post to hold the collar in alignment with the post.
