Abstract: A spring apparatus for use with hauling elements such as mooring ropes. The apparatus has a spring element (1) in the shape of a tension screw spring which has an intermediate section having a diameter considerably larger than that of its end sections (3). A certain predetermined maximal tension load, and a certain predetermined maximal stretch of the spring element are positioned at the intermediate portion, which, due to its larger diameter, has a lower spring constant, while the end-sections with their smaller diameters and larger spring constants are not stretched. The apparatus also comprises an attachment element (6) attached to an end section and preferably attachment elements attached to each of the end sections. The attachment elements are designed to hold sections of the hauling elements (10). In addition, the hauling element acts as a stretch limiter which prevents the spring from being deformed by overload.
