The invention relates to a connection element, in particular a plate nut, comprising a base body for attachment of an arbitrary component to a metallic planar object, in particular to a sheet metal.According to the invention, the base body comprises a securement portion the cross-sectional geometry of which deviates from a circular shape, the securement portion being at least partially positively receivable in a deformation in the sheet metal. The base body is, by means of a holding device, secured in the deformation against dropping out.In an alternative embodiment of the connection element, wherein unilateral accessibility to the sheet metal is sufficient, the holding device is formed by bead portions in a shaft area of the base body, which are plastically deformed into a bead by pull-out of a threaded bolt that is screwed into a thread portion.In accordance with a further embodiment the holding device is formed by a threaded nut engageable on the underside with the base body of the connection element or/and snappable onto the same, bilateral accessibility to the sheet metal however being required.
