A self-locking attachment buckle 10 for a strap 16 includes a pair of rings 12, 14 which are superposed in the form of rectangular frames having two openings 18, 20 of different size, and a transverse slot 32 for the strap 16 to pass through. The buckle 10 is located either in a blocking position after the application of a locking (gripping) force or in a position for unblocking by means of a voluntary unlocking action, giving rise to sliding of the second ring 14, and the increase in the zone of passage of the strap 16 in the slot 32 after rocking of the buckle 10. The outer edge of the crosspiece 40 of the second ring 14 is permanently set back from the parallel edge of the first ring 12 so as not to impede the rocking movement. Applications: speleology (caving), climbing, mountaineering (alpine sports), construction sites. <IMAGE> |
