• 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
• wherein the complementary means for cooperating with the clipping means comprise at least one locking lug projecting from a lateral face of the plate, said lug being configured to extend into the opening of the second part of the at least one clipping tab.
