Abstract
The buckle intended to join a belt to an anchorage point consists, among other things, of a latch (10) and of a keeper which comprises a base (20), a lock (30), an ejector guide (40), an actuating button (50), preferably a protective covering (60) and, if necessary, a closure detector (80) and an illumination device (90). This buckle comprises operating and locking means (70) which cause the lock to cooperate with the button and with the base either to allow opening of the locked buckle when the latter is subjected to a tensile force less than a given limit or to ensure permanent locking of the locked buckle when the latter is subjected to a tensile force at least equal to a predetermined value and prevent opening thereof. Application to safety belts for automotive vehicles.
