A retractor for a safety belt, comprising:

• a housing having a housing wall, a winding shaft having one end journaled in said housing wall so as to be non-displaceable axially of said shaft, a retracting spring acting on said shaft, for winding up the safety belt to be fastened to it, detent means between the housing and winding shaft and including a detent disk provided with detent elements distributed over its periphery, and being fixed to said winding shaft, and also including a counter-detent disk mounted so as to be axially displaceable on the winding shaft between the detent disk and said housing wall and having at least one counter-detent element and notches, means securing said counter-detent disk against rotation, said securing means being connected to the housing wall and extending from the housing wall approximately parallel to the winding shaft and engaging said notches in the counter-detent disk, a spring for forcing said counter-detent disk into locking engagement with said detent disk, said spring being provided between the counter-detent disk and the housing wall, and an actuating member for actuating said axially displaceable counter-detent disk for releasing said spring, said actuating member forming a pushbutton displaceable axially to the winding shaft and overreaching the detent disk in a caplike manner and having a lip gripping the counter-detent disk.
