ABSTRACT:
A waterproof device for a snorkel is mounted on a distal end of a breather pipe and has a lower shell, a ring, an upper tube with an open end, an elastic collar, and an upper shell. A lower pipe is mounted to a lower end of the lower shell and the ring is received into the lower pipe. The upper tube is pivotally connected to the ring via the elastic collar securely mounted between the ring and the upper tube. A seal board is mounted in an inner wall of the upper shell thereby achieving a water proof effect when the open end is securely connected to the seal board.
