Abstract: An overlapped end of a strap is secured to a member such as a hook by an attachment device comprising a substantially U-shaped clamp made of deformable material such as metal plate and having a flat bottom formed with a plurality of openings, a securing member including a plate body formed with a plurality of openings and rivets. Said overlapped end of strap extends between the securing member and flat bottom of the clamp for connection by press to flatten side walls of the clamp and plunge the rivets into corresponding openings in the securing member and clamp member by piercing the overlapped end of the strap with bottom ends of the rivet being hammered flat under the flat bottom of the clamp member to prevent slipping.
