A safety device for quick-fastening a tool to the end of an arm including two portions (1 and 2), one of which is attached to the arm of the machine and the other of which is attached to the tool. The first portion (1) includes a cradle (3) that is insertable under the arm of the other portion (2) having an extension (5) in the form of a hook, having at least one side lug (10) that can pass through notched openings (8, 9) in the first portion (1) and in a locking plate (6). The locking plate (6) is capable of sliding on the middle portion of the first portion (1) so as to be inserted under the hook extension (5) by springs (7). The locking plate (6) is provided with an abutment member (12) that limits the return movement of the plate (6) in order to prevent the notched openings (8, 9) from coinciding. |
