A mechanical system (1) includes a support (10), a tooth (20) and a device (30) for interconnecting the two components. The device (30) includes a key (50), a nut (60) and an elastic sheath (40) provided with a wall that is adjustable by deformation in a housing (14) of the support, by screwing between the key and the nut, between an insertion configuration and a locking configuration. The device (30) also includes a support ring (70) inserted between the key and an opening (24) made in the tooth (20). In the insertion configuration of the device (30), the support ring (70) is adjusted in the opening (24), while in the locking configuration of the device (30), the support ring (70) exerts retaining forces on the tooth (20). A heavy-construction machine bucket (G) including such a system (1), and a method for implementing such a system are also described. |
