A post-tensioning tendon comprising: a tension member including a strand and a sheath, the sheath having an outer surface; an anchor (13, 17) coupled to an end of the tension member, the anchor (13, 17) including a tubular extension through which the tension member is passed; and a sheathing retention assembly (100, 200, 300) including: an outer cap (101, 301), the outer cap (101, 301) having a tapered forcing surface, the outer cap (101, 301) coupled to the tubular extension; and one or more holding elements (103, 203, 303) positioned at least partially within the outer cap (101, 301), the one or more holding elements (103, 203, 303) each having a tapered outer surface, abutting the tapered forcing surface, the one or more holding elements (103, 203, 303) each including an inner surface, that engages the outer surface of the sheath, the post tensioning tendon being characterized in that, as the outer cap (101, 301) is installed in the actuated position onto the tubular extension, the taper of the forcing surface and the taper of the outer surface of the holding elements (103, 203, 303) serves to push or bias the holding elements (103, 203, 303) inward into contact with the sheath. a tension member including a strand and a sheath, the sheath having an outer surface; an anchor (13, 17) coupled to an end of the tension member, the anchor (13, 17) including a tubular extension through which the tension member is passed; and a sheathing retention assembly (100, 200, 300) including: an outer cap (101, 301), the outer cap (101, 301) having a tapered forcing surface, the outer cap (101, 301) coupled to the tubular extension; and one or more holding elements (103, 203, 303) positioned at least partially within the outer cap (101, 301), the one or more holding elements (103, 203, 303) each having a tapered outer surface, abutting the tapered forcing surface, the one or more holding elements (103, 203, 303) each including an inner surface, that engages the outer surface of the sheath, the post tensioning tendon being characterized in that, as the outer cap (101, 301) is installed in the actuated position onto the tubular extension, the taper of the forcing surface and the taper of the outer surface of the holding elements (103, 203, 303) serves to push or bias the holding elements (103, 203, 303) inward into contact with the sheath. an outer cap (101, 301), the outer cap (101, 301) having a tapered forcing surface, the outer cap (101, 301) coupled to the tubular extension; and one or more holding elements (103, 203, 303) positioned at least partially within the outer cap (101, 301), the one or more holding elements (103, 203, 303) each having a tapered outer surface, abutting the tapered forcing surface, the one or more holding elements (103, 203, 303) each including an inner surface, that engages the outer surface of the sheath, the post tensioning tendon being characterized in that, as the outer cap (101, 301) is installed in the actuated position onto the tubular extension, the taper of the forcing surface and the taper of the outer surface of the holding elements (103, 203, 303) serves to push or bias the holding elements (103, 203, 303) inward into contact with the sheath.
