The invention relates to a securing device (1) for a bearing ring (2) in a housing (5), comprising a base body which is essentially hollow and cylindrical in shape, and which rests, in particular, in a radial manner on the outside on the bearing ring. Said base body comprises at least one spring element which engages in an annular groove of the housing, in addition to at least one angled collar which can support the bearing ring in an axial manner. The at least one spring element (11) is hook-shaped and forms an angle from the base body (8) and extends in a radial manner towards the outside and at least partially back in the axial direction. At least one push element is formed on the securing device (1), which is actively connected to the at least one spring element (11) in such a manner that the at least one spring element (11) is prestressed and/or tensed, in particular in an axial manner, by actuating the at least one push element.
