<p>The fitting (1) has a fitting part (3) rotationally adjusted relative to another fitting part (2) about an axis of rotation. An eccentric member is rotatably inserted into an eccentric receiving space (24), and is equipped with a drive shaft (34) that is designed as a continuous journal (35). A cap (38) covers the receiving space that is opened. The cap is eccentrically designed relative to the axis of rotation, penetrates into the receiving space by an axially downward-pulled sealing edge (40), and seals the receiving space when the sealing edge is preloaded in a radially outward direction.</p>
