Coupling for the teeth of excavators and the like. The coupling between tooth and tooth-carrier is effected by means of the combination of three successive areas from the median portion of the coupling part to its free end, comprising a first area of stepped straight guides which open on the lateral outer surfaces of the coupling part, followed by an area for guiding by means of revolution surfaces, opposed to one another, and with a third, terminal area in the form of a prismatic rod having its axis coinciding with that of the part.
