a plate bearing one or more cogs, and a cog bridge mounted on the plate,
wherein the cog bridge comprises means for clipping the cog bridge onto the plate,
wherein the clipping means comprise at least one clipping tab provided in a recessed portion of the cog bridge,
wherein the at least one clipping tab comprises a first part for holding the tab extending in a main extension plane defined by the cog bridge, and a second part formed integrally with the first part and extending in a direction substantially perpendicular to the direction of extension of the first part such that the second part extends below a lower face of the cog bridge,
wherein the second part includes an opening surrounded by a continuously closed periphery,
wherein the plate is provided with complementary means for cooperating with the clipping means of the cog bridge to locking the cog bridge onto the plate in translation, and
