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

A connection element for adhering to a component surface of a first component, so that by means of the connection element, a second component is fastenable at the first component, with the connection element comprising:

• a. a base element having an adhesive side with an adhesive surface as well as an assembly structure for connecting with the second component, wherein
• b. the assembly structure is arranged on a side of the base element that is opposite to the adhesive side or arranged laterally to it, and
• c. the base element consists of a thermoplastic plastic material with a temperature of continued use of at least 130° C. which is poorly penetrable with light or not penetrable with light, and
• d. 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
• e. in the cross section, the base element has a lower thickness in the irradiation region and a transmission degree in the irradiation region is at least 20-% at a wave length of the light between 320 and 500 nm or
• f. the irradiation region is formed by a break-though.
