An incontinence treatment device includes a non-porous sling located between two anchors. A first line is attached between a first end of the sling and the first anchor, and a second line is attached to a second end of the sling and inserted through a channel of the second anchor. The second anchor is provided with a restrictor segment provided in the channel. The second line has an adjustment device attached to the second line and the restrictor segment is configured to resist movement of the adjustment device through the channel. The adjustment device is movable through the channel from a first position that locates the adjustment device between the second anchor and the sling to a second position that locates the second anchor between the adjustment device and the sling to thereby reduce an effective length of the sling between the first and second anchors.
