Connector with simplified and reliable mounting

A connector configured for connecting a first component to a second component, wherein the first component and the second component each have an opening with a respective cross section different from a circular cross section, wherein the connector comprises:

• a cage part including a radial flange at one end and a stem portion with a cross section different from a circular cross section, said stem portion being insertable into the opening of the second component such that the flange is positioned against a front side of the second component,
• wherein the connector further includes a nut part at least partially accommodated by the cage part,
• wherein the nut part is rotatable from a first rotational position in the cage part into a second rotational position,
• wherein the nut part includes an axial opening for receiving a fastening screw,
• wherein the nut part includes an outer side with opposite wing portions wherein the wing portions are configured, after rotation of the nut part from the first rotational position into the second rotational position on account of the rotation of the fastening screw in the nut part, to be pulled against a rear side of the second component when a head of the fastening screw is placed against the first component and pushes the first component against the flange of the cage part, wherein, in the first rotational position, the wing portions lie radially within an outer contour of the cage part and, in the second rotational position, the wing portions project radially beyond the outer contour of the cage part while lying against a stop of the cage part,
• wherein the nut part has a cylindrical portion with an outer diameter at an axial end, and
• wherein the cage part has a transverse surface in a region of the stem portion, wherein the transverse surface has a circular opening with an inner diameter that is larger than the outer diameter, wherein, at least in the first rotational position, the nut part is arranged or can be arranged in the cage part such that the cylindrical portion projects into or through the circular opening.
