First Claim
1. An attachment device for attaching a first object to a second object, the first object having an upper and lower surface and an edge, the attachment device comprising:
- (A) a bolt for providing a compressive force;
(B) a nut for engaging said bolt, said nut having an upper member for abutting the edge of the first object; and
(C) a body for gripping the first object, said body having a substantially U-shaped cross-section, said body comprising;
(a) an upper portion for abutting the upper surface, said upper portion having a hole for receiving said bolt; and
(b) a lower portion for abutting the lower surface, at least one nut hole for receiving said upper member of said nut, wherein said upper member of said nut extends through said nut hole and abuts the edge of the first object when the first object is between said upper and lower portions.

Abstract
An attachment device for attaching one object to another object. The attachment device comprises a U-shaped clamp, a bolt, and a U-shaped nut. The clamp has an upper and low portion and the nut has two upward projecting members. The upper and lower portions have a hole for receiving the bolt and the lower portion has two nut holes for receiving the upward projecting members of the nut. A first object is inserted between the upper and lower portions and the bolt is tightened to cause the upper and lower portions to grasp the first object. The upward projecting members prevent the attachment device from being over tightened and weakening the clamp. The members also prevent the attachment device from rotating when it is clamped to the first object. A second object may be attached to the attachment device by inserting the bolt through a hole in the second object.
