Claim:
Device for indicating tension in tension means, the device comprising: a spring which is reversely curved to form a closed end and two opposed legs extending from the closed end such that in use the spring is placed around a rigid web which forms a connection between a strap and tension means, and is surrounded in a streamlined shape by a formed loop of the strap; wherein the device allows for a recoverable deformation of the spring under tension and for a scale on which the tension can be read; a formed piece with a shape to be placed around the rigid web with the spring surrounding the formed piece at least in the bite of the loop at the closed end of the spring, the spring being combined with the formed piece in a positively engaging manner such that the tension of the tension means deforms the spring up to an end position determined by the formed piece within a lower range, and such that the tension does not further deform the spring in a second upper range of the tension since the spring contacts the formed piece in the end position—with the result that there is no overtension, and thus no change in the spring constant of the spring and in a predetermined indication range.
