Claim 9:
10. A sealing device, comprising:
a shield configured to be mounted on an outer ring of a bearing, the shield comprising an annular cylindrical wall comprising an outer lateral surface configured for mounting on an inner lateral surface of a collar of an outer ring of the bearing, the shield further comprising a circular annular wall extending radially inwardly from a first end of the annular cylindrical wall, the circular annular wall comprising an axially outer surface, and
an annular covering fixed to the shield and formed of a sealing material that is formed independently and separately from the shield and mounted on the shield, wherein an annular engagement catch is configured to allow the annular covering to be assembled by plastically deforming a portion of the annular covering and further configured to allow the annular covering to be fastened permanently on to the shield, further wherein the annular covering comprises:
a cylindrical wall comprising an axial inner surface coupled by interference to the outer lateral surface of the annular cylindrical wall of the shield; and,
a first circular annular wall extending radially inward from a first end of the cylindrical wall of the annular covering, the first circular annular wall comprising an axially inner surface configured to mount to the axially outer surface of the circular annular wall of the shield,

wherein the annular engagement catch comprises a second circular annular wall comprising a substantially radial development, which is coupled to the cylindrical wall at an opposite end from the first circular annular wall, and is coupled to an annular frontal edge of the cylindrical wall.
