ABSTRACT:
A safety device for use on looped cords of the type frequently used in pleated shades, roman shades and venetian blinds has a body containing an anvil and adjacent cord channel. The cord channel is sized to permit at least one cord to pass therethrough. A plunger having a blade attached thereto is positioned so that the blade is above the anvil. A spring attached to the plunger and the body pushes the blade away from the anvil, such that a force acting on the plunger in a direction toward the anvil will cause the blade to move toward the anvil cutting any cords within the cord channel.
