A suspension ring (1) for multistrand lifting tackle comprises two parallel rectilinear legs (2), which are connected to one another at the respective ends thereof by arcuate connecting legs (3), wherein the lower connecting leg (3) is formed symmetrically with respect to the longitudinal center line (M-M) of the suspension ring (1) and extends in a rounded shape in the form of a circular segment in the central region (5) of its extent and in the two regions (6) in which it merges into each of the two legs (2). The radii (r1, r2) of the rounded portions on the inside of the suspension ring (1) are less than half the internal width (B) of the suspension ring (1) but greater than half the diameter (d) of the legs (2), and the central region (5) in the form of a circular segment is connected at each of its ends to the transitional region (6) in the form of a circular segment to the adjacent leg (2) via a rectilinear intermediate segment (7) of the connecting leg (3), which intermediate segment is at an angle (.delta. ) in a range of from 50° to 75° to the longitudinal center line (M-M) of the suspension ring (1).
