ABSTRACT:
A link (10) of a chain conveyor has a plane (12) region terminating at at least one end thereof with an enlarged articulation element (13) projecting downwardly from the plane (12) and passed through by a hole (15) parallel to the plane (12) for the introduction of a pivot pin (11). The enlarged element (13) has at least at one end (17) close to the hole (15) opening, a plug (18) preventing the pivot pin (11) from slipping out of the hole itself. The plug (18) has facing parallel resilient arms (20, 21) terminating with undercut teeth (22, 23) projecting towards each other for fitting in corresponding rectilinear undercuts (29, 30) disposed parallelly on opposite sides of the enlarged element (13) close to the hole (15) opening. The plug (18) further comprises a projection (26) between said arms (21, 21) that is designed to be fitted in the pin-receiving hole (15) for preventing the plug (18) from sliding in at least one direction normal to the pin on fitting of the teeth (22, 23) in the corresponding undercuts (29, 30).
