ABSTRACT:
Window shade adjustment and leveling devices for controllably grasping a window shade cord for setting and leveling a window shade. The devices have a body with a button member extending into the body and having protrusions locking therein using a form of bayonet lock. Holes in the body and button member align when the button member is depressed relative to the body of insertion of the cord, with the cord being locked in position relative to the device when the button member is released. Preferably the holes in the body are specially configured to increase the gripping strength of the device, with the protrusions on the button member aiding in the gripping.
