ABSTRACT:
This snap ring has outer and inner fingers which extend slightly from the ring. Thereby it becomes possible to embrace the ends of the fingers by a plier from the outside to press the ends of the fingers towards each other and thereby to widen the inner diameter of the snap ring in a limited extent for moving the ring over a respective bar. The inner face of the ring may be circular or of angular configuration. An accessory shows especially suitable pliers for the use of handling the snap ring.
The fingers extend normal to the imaginary medial plane of the ring, the outer face forms partially by a radius around an eccentric axis of the medial plane while the inner face of the ring may form by a radius around a concentric axis of the medial plane and the roots of the fingers should be bigger in radial direction than the length of the eccentricity between the concentric axis of the inner face and the eccentric axis of the outer face to give the snap ring the strength to hold itself against axial deplacement on a metallic bar or pipe.
