A seat eliminates any danger of accident during use when attached to a suspended rope. A plate-shaped seat body (1) has an axial passage (3) and a horizontal channel (14) disposed outside of the passage (3). The rope (7) is passed through the passage (3) and has a radial section (16) which is guided over the lower side of the seat body (1) and through the channel (14) and the rope end (17) is passed beneath the radial section (16) to form a knot.
