Abstract

L'invention porte sur un système (16) de rétention mécanique destiné à retenir, de manière amovible, sur un outil (10) de terrassement, un instrument (14) venant en contact avec le sol. Le système (16) de rétention utilise un dispositif de retenue (76) allongé, en acier, qui comporte une partie ressort (86) en spires placée entre des parties terminales (82, 84) opposées du dispositif de retenue (76) de sorte que ce dernier se comprime dans un sens et puisse être monté, par une ouverture (64), dans l'appareil (14) dans une poche (38) de retenue d'une partie de fixation (20) de l'outil (10).
