Circlips/Seeger Clips/Snap Rings
Circlips are a type of fastener or retaining ring consisting of a semi flexible metal ring with open ends which can be snapped into place, into a machine groove on a dowel pin or other part to permit rotation but to prevent axial movement. There are two basic types: internal and external, referring to whether they are fitted into a bore or over a shaft. Circlips are often used to secure pinned connections.
