Interception valve, preferably sphere shaped, with fluid retainers, suitable for allowing fluid to flow in one circulation direction only, made from two separate components: a body (11) with the sphere and a union (12) with the fluid retention group (19). The two elements (11, 12) are connected one to the other so that they cannot move.
