The use of **pressure-regulating clips** on seat belts is completely discouraged for several reasons:

- **Proper belt adjustment**: The seat belt must be properly adjusted to the body, neither too loose nor too tight, so that it can effectively protect in the event of an accident. Clips can alter this proper adjustment, compromising safety.

- **Correct strap positioning**: The **chest strap** should pass over the collarbone and the center of the chest, while the **lap strap** should be over the hip bones. Clips can change these positions, increasing the risk of serious injury in the event of an accident.

- **Effectiveness of the seat belt**: A well-placed and adjusted belt doubles the chances of surviving an accident. Clips can prevent the belt from functioning correctly, reducing its effectiveness.

For these reasons, it is important not to use pressure-regulating clips and to ensure that the seat belt is always well adjusted and correctly positioned.
