The present invention provides a mounting assembly (1) for mounting an electrical function in a wall of a building. The mounting assembly (1) comprises a mounting box (10) with a back side (11), an open front side (12) and a wall (13) between the back side (11) and the open front side (12). The mounting assembly (1) furthermore comprises a carrier (20) comprising one or more components (41) of the electrical function and being attachable in the mounting box (10) via the open front side (12). The mounting assembly (1) also comprises a mounting frame (30) for mounting the mounting assembly (1) against the wall. According to the invention, the wall (13) of the mounting box (10) is, near the open front side (12), provided with at least a first integrated resilient lip (50). An inner surface (51) of the resilient lip (50) which faces the interior of the mounting box (10) is provided with a carrier guiding part (55) arranged to make the first resilient lip (50) spring outwards when the carrier (20) is provided in the mounting box. An outer surface (52) of the first resilient lip (50) is provided with a mounting frame guiding part (56) arranged to make the first resilient lip (50) spring inwards when the mounting box (10) is provided in the mounting frame (30).
