Abstract
An improved hitch for trailers characterized essentially by the fact that it is constituted by a piece of elongated shape that has two adjacent cavities at its ends separated by an intermediate partition from which the most extreme cavity is hemispherical while the adjacent cavity an axis transverse to the length of the piece in whose axis another piece forms that forms a bevelled tooth complementary to the aforesaid spherical cavity, both elements constituting a ball joint for an end ball of a pin integral with one of the vehicles.
