Abstract
A sealing plug for closing an opening in a component, in particular a body component of a motor vehicle, has a base body which is formed such that it can cover the opening and engage behind an edge of the opening. On the base body a sealing body is arranged, which includes a ring portion and several lamellae with free radial ends, which protrude from the ring portion and are flexible in circumferential direction. The sealing plug is pushed into the opening such that the rear-side latching lip engages behind the edge of the opening, wherein the lamellae of the sealing body are deformed in circumferential direction and center the sealing plug in the opening. After heating of the sealing plug a sealing material of the sealing body, which expands under the influence of heat, encloses the inner edge of the opening as well as radially adjoining regions of the front side and the rear side of the component around the entire circumference of the opening and completely fills the space formed between the supporting lip, the latching lip and the component.
