Abstract:
A slotted fastening ring for making a formfitting connection by respectively compressing or expanding the slotted fastening ring during installation or removal, comprising: a non-resilient cold-formable material and ring tips, said ring tips defining a slot, said ring tips being spaced apart, when the fastening ring is not installed, so as to be deformable towards each other under plastic deformation to a closed position with an inside opening of the ring forming a substantially circular contour, wherein the contour of the inside opening of the ring, when the ring is not installed, defines a plurality of radii (R.sub.2, R.sub.3, R.sub.4) which change gradually into each other or are adjacent to each other, respectively, wherein abutting radii (R.sub.2, R.sub.3, R.sub.4) have different lengths and have respective centers (M.sub.1, M.sub.2, M.sub.3) which are located at different points, and when in the closed position, the respective centers converge to a common center.
