A seal is provided for indicating whether a clockspring has been tampered with. The clockspring consists of a housing, a hub rotatably mounted to the housing, and a ribbon cable connected to the housing and the hub. The seal is attached to the clockspring housing and hub. The seal may consist of a tamper indicating non-marking label stock having a facestock, flexographically printed indicia located on the facestock, and an adhesive coated over the flexographically printed indicia. Furthermore, the flexographically printed indicia may provide a message such as the word "VOID." Finally, the seal may include printed instructions for inspecting the seal.
