ABSTRACT:
A guide or feeder chain for power and supply lines is provided. The chain includes chain links that each comprise two spaced-apart link members that are disposed parallel to one another and are interconnected by crosspieces. Link members of adjacent chain links, where they overlap, are held against one another via a pivot lug and a pivot hole. Disposed in each pivot axis is a locking pin that comprises a shaft, on one end of which is formed a head and on the other end of which are formed radially projecting dogs that are disposed opposite one another. Each link member, concentric to a pivot axis, has a locking hole which has radial grooves for receiving the dogs. The grooves, on one side of the link member, has undercuts that extend away from the groove in the circumferential direction of the locking hole for receiving the dogs.
