A combination lock has a latching rod, a positioning rod and multiple combination wheel assemblies each provided with a combination ring, a positioning ring and an abutting ring. Multiple detents are defined in a rear side face of the positioning ring to temporarily receive the bosses in the latching rod while the combination is not able to align the bosses with the cutout in the positioning ring such that any attempt of deducing the correct combination by pulling the latching rod and rotating the combination rings is eliminated.
