Explanation: Pons, Fachwörterbuch der Kfz-Technik, gives roll pin or hollow dowel pin. If the part is "gschlitzt, hohl, kleiner Durchmesser", it's clamping sleeve according to Pons, or "spring dowel sleevel or spring-type slotted straight pin according to Ernst, Wörterbuch der industriellen Technik. The term "locating pin" was found in Bosch, Fachwörterbuch Kraftfahrzeugtechnik. Pons also gives "split sleeve" for a pin that's "geschlitzt, hohl, grosser Durchmesser". Hope you'll find something here that fits your context!
