1. A profile clamp for connecting two tubular bodies, wherein the profile clamp comprises a clamp band having a profile cross section open radially on an inside,
wherein the clamp band has two curved clamp sections, which are connected to one another in an articulated manner, the two clamp sections each having a first transition section partially located at one end of a circumferential direction and an adjoining, radially projecting clamping element, and
wherein the profile clamp can tighten the tubular bodies by bringing each of the clamp sections closer to one another in the circumferential direction,
wherein a width of a base of the profile cross section increases uniformly toward the clamping element of one of the two clamp sections from the end of the corresponding first transition section remote from the clamping element,
wherein tangents of edges of inner surfaces on both sides of a width direction of the profile cross section over an entire circumferential length of the first transition section are angled relative to each other at a constant second angle, wherein the second angle is approximately 90°, resulting in an opening angle of approximately 45°, into which a flange can be inserted, on each side of the profile cross section, wherein the second angle is substantially constant in the first transition section.
