Abstract
A non-removable safety pin (20) for an excavator coupler for securing a latching hook thereof. The safety pin (20) comprises a head (26), a shaft (24), a distal end (22) and a longitudinal axis starting at the head (26), extending along the shaft (24) and terminating at the distal end (22), wherein either or both of the shaft (24) and the distal end (22) are keyed so as to have an element thereon that extends relative to a side of the shaft. The element prevents removal of the safety pin from a hole (36) in which the safety pin (20) is inserted.
