Closing plug for an opening in a body structure of an automobile, wherein the closing plug closes the opening against a passage of fluid and/or gas up to a limit pressure, which acts on the closing plug, and allows a passage of fluid and/or gas above the limit pressure, characterized in that the closing plug has a base body (10) consisting of a first plastic material, which has a holding section (14) with holding means for holding the closing plug in the opening and a plate-shaped head section (12) formed at one end of the holding section (14) with at least one opening (20), and in that the closing plug has a sealing body (26) made from a second plastic material which is molded onto the base body (10) in a plastic injection molding process, wherein the second plastic material is softer than the first plastic material, and wherein the sealing body (26) has at least one elastically moveable sealing arm (32), wherein the at least one sealing arm (32) sealingly covers the at least one opening (20) of the plate-shaped head section (12) from the upper side of the plate- shaped head section (12) facing away from the holding section (14) against a passage of fluid and/or gas up to the limit pressure, and wherein the at least one sealing arm (32) elastically deforms upon acting of a pressure above the limit pressure with the release of the at least one opening (20) for a passage of fluid and/or gas. |
