Abstract
The links (1) of a chain such as a tentering chain are respectively connected to each other by pins (6). In order to secure the pin against rotating and against axial shifting, an end of the pin (6) protruding beyond an outer surface of a lug (2) of the chain link (1) is provided with a radial bore (7) into which one prong (8) of a two pronged spring clip element (9) is inserted. The other prong (10) of the spring clip element (9) partially encircles the protruding end of the pin (6). A shoulder (14) projects from the outer surface of the lug (2) and a groove (13) extends into said shoulder so that a bottom (12) of the groove (13) forms a stop surface perpendicular to the lug plane. One end (15) of the one prong (8) and a transition part (11) between the two prongs (8, 10) rest against the stop surface for securely holding the spring clip element in place.
