A connecting rod has a closed bearing at one end for connecting, for exam, a piston bolt to the rod. At the other end the rod has a divided bearing for connecting, for example, a crankpin to the rod. The rod is made of fiber reinforced synthetic materials. The divided bearing is enclosed by an inner and an outer bearing bail and by a compression member. The free ends of a fiber reinforced loop which surrounds the closed bearing and the ends of the inner and outer bearing bails are formed into flanges which are interlocked by bolts. In another embodiment an endless loop is folded to form an open loop and the free ends of the open loop legs are interconnected by a bolt extending through the loop ends and through an outer bail made of fiber compound material or metal.
