A reversibly attachable fastener has a generally figure-8 geometry when in the engaged state. The fastener is composed of two generally symmetric halves, each comprising arm portions, shoulder portions, and head portions, and the halves are connected by a spring loop. One half of the fastener contains a window feature that allows the opposing, singular half to extend through and be supported in a nested fashion. The half containing the window feature has crown protrusions on the head portions which are then spanned by a bridge structure. The opposing, singular half is provided with a crown protrusion which is notched, this crown protrusion catching on the bridge structure to maintain the fastener in the engaged state. The fastener can be used to easily and reversibly attach various objects, such as keys to keyrings or identification tags to luggage. |
