Device for the detachable connection of a first tubular component and a second tubular component

A device, comprising:

• a first tubular component having a flange in an end region;
• a second tubular component embodied as a screw nut, wherein the screw nut has an inner diameter greater than an outer diameter of the flange of the first tubular component such that the screw nut can be applied over the flange onto the first tubular component, wherein the screw nut has two parallel passages located on chords through an outer wall of the screw nut;
• and
• a clamp having:
• two parallel inner brackets that correspond to the two passages of the screw nut;
• two parallel outer brackets that are parallel with the inner brackets;
• and
• a connecting surface that connects the two inner brackets and the two outer brackets, the two inner brackets and the two outer brackets merging into the connecting surface,
• wherein the inner brackets, the outer brackets, and the connecting surface are co-planar,
• wherein, in an assembled state, the two inner brackets are inserted into the two passages of the screw nut and engage the first tubular component behind the flange, the two outer brackets engage an outer surface of the screw nut, and the screw nut is thereby fastened to the first tubular component in connection with the flange of the first tubular component.
