Abstract
A pull rope shortening device for fire extinguishing units, particularly for kitchen exhaust hoods, includes a shortening element which deflects the pull rope which is under tension in order to shorten the length of the pull rope, wherein the shortening element is held in the position in which it shortens the length of the pull rope by a thermally released separating device. The shortening element is composed of a spring steel wire which is wound or bent in such a way that at each end thereof is formed an end eyelet for receiving the pull rope and at least one guide eyelet acting as a spring and guiding the pull rope is provided between the two ends.
