Arrangement of a separate functional element of a washer water reservoir on a fixing portion of a structural component

An arrangement of a separate functional element of a washing fluid reservoir on a fixing portion of a structural component of a motor vehicle, wherein:

• the functional element has side surfaces that extend substantially in a vertical direction of the motor vehicle;
• the structural component has a side surface that extends at an oblique angle relative to the vertical direction of the motor vehicle, and the fixing portion thereof has an installation surface that is substantially parallel to the side surface of the structural component and also extends at the oblique angle relative to the vertical direction of the motor vehicle;
• the functional element has an attachment member that extends from a side surface thereof at the oblique angle and that comprises an insertion portion;
• the fixing portion is at least partially made of a plastics material, and
• an opening is formed in the fixing portion in such a way that the attachment member of the functional element is configured to be brought into a final installation position by inserting and sliding and/or rotating the insertion portion in a direction transverse to the depth direction of the opening,
• wherein the functional element in the final installation position, viewed in the depth direction of the opening, is fixed positively with respect to the structural component;
• and
• further comprising a resilient locking tab on the attachment member of the functional element which, in the final installation position, causes the functional element to be positively fixed relative to the structural component in such a way that the functional element is blocked positively from sliding back and/or rotating back out of the final installation position.
