A clamp frame is disclosed for securing a window frame in a building structure opening by hand without using fasteners. The clamp frame comprises a unitary extruded plastic member that defines a cross section having an integrally formed connection element that mates with a complementarily shaped portion of a window frame to connect the clamp frame and the window frame without fasteners along the length of the clamp frame. The cross section includes a clamp element having at least a leg and a lever. The leg and lever are each connected to the connection element by a living hinge and are movable relative to the connection element between an open position and an overlapping locked position, which results in a clamp load holding together the clamp frame and window frame without the use of fasteners. One end of the leg of the clamp element is constantly urged against the building structure by the lever when the clamp element is in the locked position. The clamp frame may be preassembled by hand onto the window frame before shipping to customers.
