A compression device, useful for applying circumferential compression to an object, includes a simplified cinch mechanism. The device includes a guidance slide, a jamming feature/pull tab, a buckle assembly and a cinch strap, which form a loop for placing about an object. The cinch strap includes both an inner portion, anchored to the jamming feature, and an outer portion, anchored to the guidance slide. The inner portion of the cinch strap passes through the guidance slide to an adjustable, locking side of the buckle assembly, and the outer portion of the cinch strap passes from the adjustable, locking side of the buckle assembly to the guidance slide. The cinch strap can move freely when pulled on by the inner portion and lock when pulled on by the outer portion, such that an inner circumference of the device is adjustable but can maintain a minimum circumferential length after tension is applied.
