1. A sealing device for a turbine engine bearing oil enclosure, comprising:
a rotor shaft;
an annular cover secured to an engine casing and arranged around the rotor shaft to co-operate therewith to define an oil enclosure that is to receive a bearing rotatably supporting the rotor shaft relative to the engine casing;
a labyrinth seal mounted on the rotor shaft facing one end of the cover;
an annular rim mounted inside the cover;
a dynamic annular gasket interposed radially between the rim and the rotor shaft; and
a clip for axially blocking the rim inside the cover and including at least one latch passing radially through an annular groove formed in the rim and being received radially inside a groove formed in the cover.
