Union between cylindrical components - has internal space between them with spring lug bent inwards to snap into engagement behind outer edge of second compartment

摘要

The union between two cylindrical components (1,2; 1',2') incorporates an internal space formed between them. This accommodates a spring lug (4) bent inwards, so as to snap into engagement behind the outer edge (5) of the second component (2), and formed on the first one (1). An annular tool (6) acting in the peripheral direction forces the lug outwards to detach the components from each other.
