Connection element for adhering to a component surface and production method and securing method therefor

A method for fastening a first component to a second component by means of a connection element comprising a base element having an adhesive side with an adhesive surface as well as an assembly structure for connecting with the second component, wherein the assembly structure is arranged on a side of the base element that is opposite to the adhesive side or the assembly structure is arranged on a side of the base element that is arranged laterally to the adhesive side, and the base element consists of a thermoplastic plastic material with a temperature of continued use of at least 130° C. which is not penetrable with light, and the base element comprises at least one irradiation region so that the base element is irradiatable with light in the irradiation region such that light energy penetrates the base element, wherein

• the irradiation region is formed by a break-through and with the break-through being closed by a coating which consists of a material that is irradiatable with light and with the coating closing the break-through from the adhesive side of the base element, and the method for fastening comprises the steps:
• a) arranging an adhesive, which cures by means of light beams, on the adhesive side of the base element and/or the first component,
• b) arranging the adhesive side of the connection element on the first component,
• c) irradiating the arrangement out of the first component and connection element arranged thereon with light, so that the adhesive realizes in the irradiation region at least a pre-fixing of the connection element, as well as
• d) curing of the adhesive.
