A locking mechanism for a seat belt has a case (1), a locking set (20) and a pretensioner (30). The case (1) is mounted adjacent to a side of a retractor (50) having a shaft (51) and the case (1) is mounted around the shaft (51) and has a mount (12) inside the case (1) and at least one opening (42) being formed on the bottom. The mount (12) has at least one hole (121) formed therethrough. The locking set (20) is mounted on the shaft (51). The pretensioner (30) has a steel ball (31) and a rod (32). The steel ball (31) is detachably disposed on the mount (12) and the rod (32) is pivotally mounted in the case (1) and is disposed on the steel ball (31). If muddy water, sand or dirt enters the locking mechanism, muddy water, sand or dirt can fall through the at least one hole (121) of the mount (12) and the at least one opening (42) thus avoiding muddy water, sand or dirt affecting the locking mechanism.
