A quick-connect buckle is provided for a tourniquet, the quick-connect buckle including a dovetail tongue and groove coupling system with an initial coupling position and a final coupling position corresponding to a tensioned configuration. The quick-connect coupler also has application beyond use in tourniquets. Accordingly, the quick-connect coupler can be combined with a strap to form an all-purpose binding device used for a variety of purposes. Methods associated with the quick-connect buckle are also described.
