    Abstract: A safety ring for a window blind has a ring and a connector. The ring has a gap. The connector is connected to the ring and has multiple tabs detachably mounted through and engaging the gap of the ring. When a cord passing through the ring is pulled by lateral force, the connector attached to a shade will disengage from the ring. Therefore, the window blind is safely used and prevents children from being wrapped in the cord.
