An assembly () of moulding elements for moulding cuts in a tread of a tire comprises a first sipe blade (), a second sipe blade () and means for assembling the first sipe blade () with the second sipe blade (). The assembly means comprise at least one slot () in the thickness of the first sipe blade (), said first sipe blade () having no additional thickness at said slot () and a protuberance () in the continuation of the second sipe blade (), said protuberance () being able to be inserted into the slot (). This assembly system is both simple to produce and allows a multitude of configurations of the sipe blades relative to one another.
