SUPPORT FLANGE FOR FLEX TUBING

The flange (200) includes a hollow base (210) having an open top side， two opposite open ends， and an inner wall (212) which borders a bottom side as well as two opposite side sides of the base (210). The internal wall (212) defines a passage (214) extending between the two opposite open ends and through which a flexible tube (202) can pass. The flange (200) also includes a sliding part (220) inserted into the base (210) by one of its ends to close its upper side. The proposed concept is particularly advantageous for maple growing.
