Abstract

A securing element (1, 11, 12, 13, 14) made of sheet metal with an annular body (3, 12a, 26) and with holding tongues (4, 41, 42, 43, 44) which emerge from the annular body (3, 12a, 26) and end at a hole (6) in the securing element (1, 11, 12, 13, 14), which hole is centered with respect to the center axis (5) of the securing element (1, 11, 12, 13, 14), wherein the hole (6) leads axially in the same direction as the center axis (5) through the securing element (1, 11, 12, 13, 14) and, at radial narrowest hole cross sections of the hole (6), is bounded at least by end edges (7, 71, 72, 73, 74) formed on the end sides of the holding tongues (4, 41, 42, 43, 44).
