A device (1) for attachment to a restraining belt is disclosed comprising a casing (3) for enveloping widthwise the restraining belt; a cam (5) rotatably mounted in the casing (3) along an axis extending substantially parallel to the length of the belt, and an element (7) for rotating the cam (5) from a neutral position in which the cam (5) does not make contact with the belt, to a clamping position in which the cam (5) grips the belt. A restraining belt system incorporating the device (1) is also disclosed. The device (1) obviates the problem of tension exerted on wearers of restraining belts, is both safe and cheap to manufacture and can be fitted easily to existing vehicle seat belts. |
