A plug component for an electrical control unit has a contact section formed with one or more compartments, in which a number of contact pins extend perpendicular to a first reference plane. The plug component can be contacted mechanically and electrically with a plug via the contact section. An attachment section extends along the first reference plane and comprises a number of sealing sections, which are provided for resting against corresponding sealing sections of at least one housing component of the control unit. A first of the sealing sections runs in parallel to the first reference plane. Second sealing sections curve away from opposing free ends of the first sealing section and extend in a second reference plane which is arranged perpendicular to the first reference plane.
