Abstract (en)
[origin: WO2015036936A1] The device (1) for securing teeth (3) to a tooth adapter (4) of an earth-moving machine comprises a pin (10) to be removably inserted through at least one first aperture (12) on a tooth (3) and one second aperture (14) on a tooth adapter (4) of a machine. The pin (10) comprises at least one expanding element (20) adapted to reversibly switch from a retracted position to an extracted position by moving in a plane substantially perpendicular to the longitudinal axis (x-x) of said pin (10). The device (1) further comprises at least one retaining element (22) associated with at least one of said first and second apertures (12, 14), and provided with at least one seat (24) for at least partially receiving the expanding element (20) when said expanding element (20) is in said extracted position.
