ABSTRACT:
An apparatus for fixing the sheathing of an end of a tendon within an anchor body of a post-tension anchor system has an anchor body with a cavity formed therein, a tendon extending into the cavity, a fixing element engaged with the sheathing of the tendon for fixing a position of the sheathing on the tendon, and a pair of wedges in engagement with the unsheathed portion of tendon within the anchor body. The fixing element is positioned within the cavity. The fixing element can either be a wedge member interposed between the sheathing and the tendon so as to frictionally engage the tendon or a clip member engaged with the sheathing.
