ABSTRACT:
A cord locking device includes a channel-shaped housing within which a roller is rotably mounted. Oppositely positioned slots within the housing carry a serrated second roller down and away from said first roller, said serrated second roller travels along a grooved wall section, which has a bent portion at the lowermost portion thereof, permitting the second roller to rotate free of the wall at that position. A cord is trained over the first roller and is locked thereto or freely movably depending upon the position of the second roller.
