An anti-strangulation apparatus for, and hanging freely with, a looped cord of a window covering device. The apparatus includes a tube. The tube at first has the looped cord of the window covering device enter therein, then has the looped cord of the window covering device exit therefrom and run therealong, and then has the looped cord of the window covering device reenter therein again where the looped cord of the window covering device is reeved, and in so doing, the anti-strangulation device is allowed to hang freely with the looped cord of the window covering device and keep the looped cord of the window covering device snug enough against the tube to prevent strangulation by the looped cord of the window covering device, while allowing the looped cord of the window covering device to remain fully operational.
