Abstract
A window covering and tighteners of the window covering are provided, wherein each of the tighteners is a closed frame having an inner surface and an outer surface. The space surrounded by the inner surface forms a through hole and a gap which are communicated with each other, wherein the through hole allows a cord, which moves a bottom rail relative to a headrail of the window covering, to pass therethrough, and the width of the gap is less than the diameter of the cord. Whereby, if the cord is accidentally pulled away from the shades laterally or horizontally, the cord quickly and smoothly enters the gap to be tightly bitten therein. The cord is hence stopped from being further pulled outwardly to form a hazardous loop which may cause serious injuries to users.
