A hand-held power tool, comprising:

• a housing;
• and
• a rechargeable battery pack, wherein the rechargeable battery pack includes guide elements;
• wherein a housing interface unit of the hand-held power tool is provided on the housing and cooperates with a rechargeable battery pack interface unit of the rechargeable battery pack in such a way that a mechanical and electrical connection between the hand-held power tool and the rechargeable battery pack is established,
• wherein the housing interface unit includes at least one guide bar engageable with the guide elements of the rechargeable battery pack and includes a contact plate which has at least one contact element configured for electrical contacting with countercontact elements of the rechargeable battery pack, and wherein the contact plate also includes at least one retaining element for additional fixing of the rechargeable battery pack interface unit to the contact plate,
• wherein the fixing of the contact plate in the housing interface unit is at least partially achieved by the at least one retaining element,
• wherein the at least one retaining element is configured as a hook-shaped structure on the contact plate, wherein an inner surface of the hook-shaped retaining element includes a wedge-shaped formation, as the result of which, when the rechargeable battery pack is inserted into the housing interface unit, the guide elements are pressed against the underside of the contact plate in such a way that a fixed connection is created between the rechargeable battery pack interface unit and the contact plate.
