Disclosed herein is a conveyor comprising a first mayor element including an end comprising an interiorly located eye including therein an opening, and an end eye adjacently spaced from the interior eye to define therebetween a space and including therein an opening located in axial alignment with the opening in the interiorly located eye and having a given dimension, a second conveyor element including an end comprising an eye extending into the space between the end eye and the interiorly located eye and including therein an opening axially aligned with respect to the openings in the end eye and the interiorly located eye, and a hinge pin including a cylindrical portion extending in the opening in the interiorly located eye of the first conveyor element and in the opening in the eye of the second conveyor element, and an axially outwardly diverging conically shaped end portion extending axially from the cylindrical portion and including a diametrically and axially extending slot defining opposed barbs having outer ends located in adjacent relation to the end eye and having a dimension greater than the dimension of the opening in the end eye so as to normally be impassable through the opening in the end eye, whereby to normally prevent axially outward passage of the hinge pin through the end eye and whereby to permit passage of the hinge pin through the opening in the end eye when the barbs are displaced toward each other.
