A retractor for storage of a long, flexible line includes a thin, flat, elongated strip spring member of tough, resilient, inelastic resin, preferably an oriented polyester resin such as polyethylene terephthalate, the spring having an arcuate configuration exceeding 180 DEG up to a full 360 DEG . A plurality of small pulleys mounted on the spring member project inwardly thereof at spaced locations with half of the pulleys located on each side of a centerline. The line is anchored to the spring member near one end of the centerline and extends back and forth across the centerline around each pulley to store a substantial length of the line within the spring member.
