A chain link having a pair of spaced sidebars provided with a set of aligned bores and a round pin positioned within so as to extend through the aligned bores utilizes sidebars and a pin which cooperate in a manner which positively secures the pin in position within the bores and which accommodates a removal of the pin from the bores in a manner which prevents damage to the link components. The pin has a head on one end and an annular rib on its other end, and the sidewall of one of the aligned bores possesses a diameter which tapers in size from one end of the bore to the other end thereof and is adapted to flex outwardly to accommodate the passage of the annular rib therethrough.
