Bayonet lock-snap ring for e.g. drilling clamp, has sections lying above each other, where height of one of sections is varied along another section so that overall height of ring is varied with respect to degree of overlapping of sections

摘要

The ring (1) has two sections (2, 3) acting together and lying above each other. The sections are extended in a wedge shape and/or conical shape, and include an anti-skid device (4) at an overlapping surface. Height of one of the sections is varied along another section so that entire height of the ring is varied with respect to a degree of overlapping of the sections, where the ring lies between a pipeline fitting outlet and a fitting, and ensures a bayonet connection between the outlet and the fitting against axial detachable movement.
