Abstract: A fishing rig retainer for attaching a seondary fishing rig to a primary fishing line comprises a body that slides along the primary fishing line and a clamp attached to the body for holding the body in a selected position on the primary fishing line. The secondary fishing rig is operably connected to the clamp and causes the clamp to release when a fish takes the secondary fishing rig. This lets the body slide toward the end of the primary fishing line and facilitates release of the primary fishing line from a downrigger release clip.
