Abstract
A tensioning device for the cord loop of a window treatment apparatus includes a cord guide disposed in a housing, a biasing element such as a spring and a locking member that locks the cord guide into an installation position. During installation, the cord guide is fixed so that it cannot move and does not affect the tensioning of the cord. After installation, the locking member is removed and the cord guide can move in one direction or another to properly tension the cord.
