Improved valve for hichables, characterized essentially by the fact of being constituted by an interior piece to the inflatable of an inverted truncated cone shape, provided with windows for the passage of air in its side wall, because said truncated cone is open at its greater base and joined by its periphery to a flexible surface in the manner of a bell that is located on the outside of the inflatable and which is topped by a cylindrical neck of air intake; because the side wall of the cone trunk inside the hichable has a series of windows for air passage, and because a cylindrical core located in the projection of the air inlet neck emerges from the lower base of said cone trunk, which allows that when the flexible flared surface is folded over the inner part of the valve, the adjusted insertion of the core into the neck occurs, establishing the closure of the valve.
