Abstract
Abstract A strap connection means for pack frames wherein: a body member is provided with a slot and a folded strap is disposed in Ushaped disposition with the strap folded against itself and a retainer is disposed in the folded portion such that the thickness of the retainer and the strap folded on opposite sides thereof have an aggregate breadth greater than the breadth of the slot so that when the strap portions are pulled into the slot the retainer prevents the folded strap from being pulled through the slot and thereby locks the strap to the body. The body may be provided with either a horizontal bore or a vertical bore therein for connection to horizontal or vertical tubular frame members of a pack frame, or may be fixed to a flat plate-like pack frame. The strap portions fixed to the body may be adjustably disposed therein and connected to shoulder engaging straps or hip engaging belts of the frame suspension means of a pack frame.
