Inspiration valve has body in form of hollow cylinder, air duct inserted into branch pipe of unit combining mouth-piece and expiration valve. Inspiration valve frame is fitted on one end of its body and other end is provided with circular projecting bead whose thickness is equal to thickness of wall of said branch pipe of air duct connected with tube by means of rubber adapter. Attachment protecting tube against flooding is made in form of mini-bell having shape of sleeve with semispherical bottom screwed to upper end of tube coaxially relative to it. Sleeve is closed from below with plane inclined inside it and provided with seats for air inlet holes. Float has inclined upper surface coated with rubber for closing the inlet holes at diving.
