<p>The invention relates to a device for arranging, clamping or contracting a ring-shaped securing mechanism. The inventive device has at least the following elements: an open clamping ring (3) with a securing section (5, 7) at each end; and at least two clamping jaws (11) located inside said clamping ring, said clamping jaws being bent into a ring shape and essentially meeting, laterally. The clamping jaws rest against the clamping ring (12) with their outer edge (12) and together at least almost form a circular opening with their inner surface (19). The device also has at least one spring-type mechanism (15), each spring-type mechanism being situated respectively between the laterally contiguous clamping jaws in order to drive them apart or to part the clamping ring in its non-clamped state, in the direction in which the ring opening diameter increases and to secure the clamping jaws in the clamping ring. The open clamping ring can be clamped in the direction in which the diameter decreases by means of a clamping mechanism with at least two engaging sections which are provided for engaging with the securing sections.</p> |
