1. A device for indicating the wear on a brake lining of a disc brake, which triggers a signal when the brake lining reaches a predefined wear limit, comprising:
a circlip (10), and
a sensor (32) having a sensor head (34) configured to be fastened in a brake lining, wherein the sensor has a groove (36) that receives the circlip (10), for securing the sensor (32) to the brake lining,
wherein the groove (36) has a flattened region, and the shape of the circlip (10) is matched to the flattened region;
wherein the groove extends circumferentially around the sensor head,
wherein the circlip includes two end portions defining two opposite terminal ends of the circlip;
wherein each of the terminal ends are disposed in the flattened region of the groove.
