The invention relates to a device (100) and a method for establishing an electrical connection between an electrical traction energy store of a motor vehicle and a high-voltage on-board electrical system, and to a motor vehicle having such a device (100). The apparatus (100) comprises a housing (12), preferably made of metal, and a battery junction box device (10) connected or connectable to the housing (12) by a first detachable connection (22). A battery junction box device (10) is provided with a switching device (30) and an anti-touch member (16). A switching device (30) is arranged on the carrier plate (14) and is configured to selectively establish or disconnect an electrical connection between a first terminal (18) for connecting an electrical traction energy store and a second terminal (20) for connecting a high-voltage on-board electrical system. A touch protection member (16), preferably made of plastic, is configured as a cover for covering the switching device (30) and is connected or connectable
