The fixing device is cheap and facilitates the mounting of the derailleur on the frame lug. This is achieved in providing on the support of the derailleur a wedging device which is rotatably mounted on the support with a high degree of friction and is adapted to cooperate with the frame lug. The support further comprises preferably an elastically yieldable device which is capable of clipping in the slot of the frame lug so as to center the support. |
