Abstract: A clip includes an exterior perimeter and two opposing flaps. The two opposing flaps may share a common end, with one flap extending out of the plane of the exterior perimeter. Rotation of the flap extending out of the plane towards the plane of the exterior perimeter rotates the opposing flap to open the clip. The clip may include a hook or other attachment feature such that the clipped object may be secured to a second object. In an exemplary application, the clip is used with a fishing line and pole to secure the line between the clip and hook the line to a pole for storage or transport.
