Abstract
A cartridge for retaining a sheathing of a tendon within an anchor assembly has a generally tubular body with outer and inner surfaces, and at least one wedge positioned within the tubular body and against the inner surface thereof. The wedge has a surface opposite the inner wall that engages with the sheathing of the tendon. A seal is affixed to an end of the tubular body which is suitable for sealing against an anchor of the anchor assembly and an inner surface suitable for sealing against the sheathing. The inner wall of the tubular body tapers so as to narrow in inner diameter from one end thereof. The wedge has a surface bearing against the tapered portion of the inner wall of the tubular body. A protrusion extends outwardly of the tubular body so as to be received within a slot of a tubular extension of the anchor assembly.
