Device for the quick fastening of a working tool (9, 110) on an arm of a machine, especially a public works machine, comprising a first part (1, 101) carried by an arm of the machine and second part (8, 109) fixed to the tool (9, 110). One of the first and second parts are equipped with first and second bearing members (6 or 106, 7 or 108), and the other part is equipped with hook-shaped first bearing elements (16, 117) adapted to receive the first bearing members (6, 106) and with inclined second bearing elements (17, 120) adapted to interact by wedging with the second bearing members (7, 108). One of the first and second parts also carry a locking member (31, 123) which interacts with a complementary locking member (12, 113) carried by the other part, after the engagement of the bearing members (6 or 106, 7 or 108). The locking members contributed to the wedging of the second bearing members in relation to the inclined second bearing elements (17, 120) to tightly secure the tool to the machine without play. |
