Abstract

The invention relates to an assembly for coupling wear parts on tool holders for civil engineering machines comprising a tooth and an adapter with a feather key. The inventive assembly is characterised in that the tooth and adapter are connected by bearing profiled matching shapes on different planes arranged between the respective contacting and connecting ends thereof and said shapes are symmetrically and oppositely placed on the top and lower faces of the adapter and tooth nose.
