A chain intended for pipe flange connections comprising successive, cross-sectionally U-shaped chain links 8, which are hinged directly to each other and form a ring sector-like contact area 14, 15, 17 and 18. At the contact point of the chain links 8, following on to the eye ring 9, an interstice 13 is provided. Moreover, an interstice 11 is likewise provided between the two flanks 31, 32 of the U-shaped chain links 8 and the two pipes 1, 2 to be connected. The contact points of the chain links 8 are designed as level annular segmental contact surfaces 17, 18 and rest on the likewise level, chamfered outer surfaces 14, 15 of the pipe flanges 3, 4.
