A stopping device for tape measures, consisting of a lower housing, a locking button, a spring, a tape roller and an upper housing, arranged in such a way that when the locking button is pushed upwards, the lower part of the stopping spring is released from the outer stopping rim of the tape roller which allows the tape to be retracted automatically using the tension of the helical spring of the tape roller, and releasing the locking button allows the tension of the helical spring to return to its initial position, thereby pressing against the outer stopping rim on one side of the tape roller and providing the mechanism for stopping it.
