Abstract: A clamp having an U-shaped clamp body (1) which engages a profile such as a rectangular or square pipe (2) on three sides (3, 4, 5), while the fourth side (6) of the profile is engaged by a bolt (7) which is secured by a nut (8) and extends through conical holes (9, 10) in the free legs of the clamp body (1). Conical washers (11, 12) on the bolt (7) engage the conical holes (9, 10) on the far side from the pipe (2), meaning that the bolt (7) is located somewhat eccentrically in the holes (9, 10). Tightening the bolt (7) by means of the nut (8) makes the clamp body (1) squeeze the top side (3) and bottom side (4) of the pipe (2). The conical washers (11, 12) in the conical holes (9, 10) make the bolt (7) squeeze the pipe (2) in the direction of the back side (5) of the pipe. The pipe (2) is thus squeezed from all sides, giving a strong and stable clamp connection.
