Control cable adjustment device

A control cable adjustment device (20) for adjusting a control cable extending between a control mechanism and an operating mechanism. The adjustment device includes an adjuster rotatably connected to a housing of the control mechanism and a spring element (2) having at least one retention segment (6). The retention segment (6) engages a detent contour (5) of the adjuster (1) to retain the adjuster (1) in its current position. Another segment of the spring element (2) may have a second function as a return spring for a gear shifter or a brake lever. However, if the spring element (2) does not serve a dual purpose, the spring element (2) has a holding segment (18) that is braced against an existing control cable installation opening in the housing (17) of the control mechanism.
