A ring fastener, with a circular configuration in the rest condition, comprising two ring ends (11, 12) spaced from each other, an essentially constant cross-section over at least 150 DEG of its circumference, and in the area of each ring end (11, 12) a recess (13, 14) opening toward its inner circumference, enables an easy installation. A special apparatus enables a particularly effective installation of the ring fastener in very confined conditions. |
