Multi-part socket-like cement-in retainer

A multipart socket-shaped glue-in retainer which is fastenable in a component opening in an adhesive manner and which is configured in at least two parts due to an axial separation and thus in an opening manner in a radial direction, so that:

• only before a gluing-in of the glue-in retainer in a component opening, a functional insert is arrangeable in the glue-in retainer, and
• after the gluing-in of the glue-in retainer in the component opening, the functional insert is retained inseparably in the glue-in retainer, wherein:
• the glue-in retainer includes a hollow-cylindrical receiving body with a circumferential lateral area, a closed axial face side, and an open axial face side with a functional opening which is provided opposite to the closed axial face side, wherein adjacent to the functional opening of the open face side, a circumferentially surrounding fastening collar is arranged, extending radially outwardly with respect to the lateral area of the receiving body so that in use the fastening collar abuts a component surface while the remaining receiving body extends into the component opening, and a circumferentially surrounding web projecting in axial direction is provided at the side of the fastening collar which faces the component so that the web delimits a channel at the component-facing side of the fastening collar in which adhesive is receivable, wherein the fastening collar has a plurality of evenly distributed recesses at its side facing away from the component, wherein within the recesses, the thickness of the fastening collar in the direction of the longitudinal axis is reduced so much that a bottom of the recess is irradiatable with light.
