Pin for coupling between a wear element and a support of an earth-moving machine and coupling system

A pin for coupling between a wear element and a support of an earth-moving machine, comprising:

• an elongated body with two curved surfaces, a concave upper surface and a convex lower surface, the concave upper surface having an upper orifice for access to a cavity inside the body;
• an elastic block arranged inside the cavity of the body with an upper surface;
• and
• a latch partially housed in the cavity of the body, said latch having:
• a curved outer surface;
• an upper surface and a lower surface, connected by the curved outer surface, the lower surface being in contact with the upper surface of the elastic block;
• a partially curved intermediate surface opposite the outer surface and after the upper surface;
• two flat side surfaces;
• and
• a cylinder configured as a rotation shaft of the latch, the cylinder arranged between the intermediate surface and the lower surface, the ends thereof extending beyond the flat side surfaces of the latch;
• and
• wherein the upper surface of the latch comprises a slot.
