Abstract: A fastener system mounts a pouch onto a shirt or other clothing article, wherein the pouch provides a receptacle aperture into which a fastener is placed with its flanges positioned on opposing sides of the aperture. The cloth to which the fastener is mounted is gripped between the fastener and the aperture and is locked into place by a U-shaped clip. The flanges are made oblong in shape so that the narrow orientation of the flanges easily pass through the aperture, but the longer orientation cannot. Flats may be applied to both aperture and the fastener so as to assure an orientation in use wherein the fastener cannot disengage from the pouch.
