Claim:
1. A system for holding flat straps, the system comprising: a device body, the device body having an attachment area for attaching a strap and a cam area for adjustably attaching the strap; and a hub, the hub constrained within the cam area by a pivot pin and oriented in the cam area such that the hub may rotate to capture the strap between the hub and the device body; wherein the hub includes an arm that is nearly tangential to the hub, the arm having a gripping surface and the body includes a gripping portion and the cam area is a cavity in the device body wherein the cavity has an entrance, a top part of the entrance having the gripping portion of the body and the gripping surface of the arm has a bottom portion of the arm that is nearly tangential to the hub, and the top part of the entrance having a side opposite the gripping surface of the arm and a surface of the body has a bottom portion, and wherein the strap may be fed through a bottom part of the entrance around a rotation point of the hub and over the arm and out of the top part of the entrance and where the hub is positioned to rotate; and the gripping surface extends from the arm that is nearly tangential to the hub, the arm having a plurality of raised protrusions which extend substantially perpendicularly from the arm toward the gripping area, the gripping surface positioned such that it opposes the gripping portion of the body such that as the strap that is fed through the bottom part of the entrance around the rotation point of the hub and out of the top part of the entrance is pulled out of the bottom part of the entrance, the strap causes the hub to rotate towards the gripping portion of the body and the gripping portion and gripping surface holds the strap, the hub may rotate around the rotation point and, during rotation, moves closer to the gripping portion when applying a tensioning force to said flat strap and farther away from the gripping portion when the tensioning force is removed from said flat strap.
