<p>A clamping device for clamping a structure, such as a door or window case, into a frame of substantially U-shape cross-section and which has an inner web wall with an offset portion and a sidewall on each side, comprises, a clamping body of substantially U-shape cross-section. The clamping body has a back web wall adapted to be secured to the structure and a leg wall on each side of the web wall which extends outwardly therefrom. At least a portion of the length of each of the leg walls is resilient so that it may be bent inwardly or outwardly. The substantially U-shaped abutment has a back abutment wall which is adapted to be slidably engaged into a receiving groove at the offset portion of the frame. It includes an abutment sidewall on each side which is disposed alongside the respective ones of the leg walls. A clamp member is movably disposed between the side leg walls of the clamping body and it is displaceable to move these walls into clamping engagement with the sidewall of the abutment. This clamping interengagement is effected by a set screw which is threaded through the offset portion of the frame and through both the side leg walls of the clamping body and the abutment sidewalls and into the clamp member so that rotation of the set screw effects shifting of the clamp member to cause the movement of the side leg walls into engagement with the abutment walls and effect the clamping of the structure in the frame.</p> |
