A housing for an electrical machine includes a cover with an electrical plug connection. The plug connection includes at least one electrically conductive contact or a plurality of electrically conductive contacts configured to electrically connect the housing to a plug. The contact is routed through an aperture in the cover and forms an electrical plug contact via an end section that projects out of the cover. The plug connection has a securing element that extends in a flat manner. A lateral dimension of the aperture in the cover is formed such that the contact is routed through the aperture via the end section and engages behind a projection in an interlocking manner by virtue of moving transverse to the longitudinal extent in the aperture. The securing element has at least one aperture that is configured to fix the contact in the aperture transverse to a longitudinal extent of the contact.
