The setting discs have setting symbols and detent engage in individual angular positions. Locking sleeves are adjacent and cooperate with the setting discs. A spring-biased rocker has feeler projections with feeler surfaces which cooperate with engagement spaces in the locking sleeves. The rocker is adapted to engage a mating locking part of the lock. When the lock combination is properly set, the engagement spaces lie in respective positions opposite the feeler projections. The rocker comprises a U-shape including U-arms which surround the setting discs and the locking sleeves. The setting discs are mounted on respective shafts, and the rocker has an axis extending transverse to a plane through the respective shafts of the setting discs.
