Abstract: A one-piece clamp assembly for a window covering is disclosed. The window covering consists of a left side portion and right side portion connected to a moveable hinge portion. The left side portion comprises a plurality of rounded extrusions and at least one vertical rounded extrusion that securely mates into a hole or slot on the right side portion. The left side portion further comprises extruded walls that mate with single and double spikes found on the right side portion. The extruded portions and mating spikes provide for a secure connection of the clamp assembly to the window covering. A connecting slot is placed on either the left or ride side portion, enabling the clamp assembly to fasten to a head rail fastener of a window covering.
