Abstract: An improved channeling for hydroponic or similar cultivations, being of the type that is made up of a plurality of gutter shaped channelings that have a shape that is noticeably “U” shaped, said portions of channeling being connected to each other by means of some fixing means that are arranged at the ends of same, and are basically characterized by the fact that the fixing means have a coupling piece made of a semi-rigid mouldable plastic material made by injection with a shape that is appreciably “U” shaped that coincides with the profile of the portion of the channeling, there being an inner lateral wall and a second outer lateral wall on the outside of the first so that there is a groove between the two lateral walls which will be used for the insertion of the portion of channeling, there also being a perpendicular separation wall along the complete perimeter inside said groove, and comprising some means of fitting by pressure that overlaps the outer lateral wall of the coupling piece that are for the cou
