An automatically locking retractor comprising a housing, a spool disposed within the housing, and a belt connected to the spool. The belt is windable between a fully extended position, a fully retracted position, and a partially extended position. A spool-locking mechanism is engageable with the spool while the belt is moving between the partially extended position and the fully extended position. Indicia is mounted on the belt for alerting the user that the spool-locking mechanism is engageable, wherein the indicia is exposed outside of the housing when the spool-locking mechanism is engageable. The spool-locking mechanism may be actuated by a clutch ring that frictionally engages the spool. The clutch ring may be biased into frictional engagement with the spool by a wave spring, or may be held in frictional engagement with the spool by magnets.
