ABSTRACT:
A splash protector mounted at top of snorkel is disclosed and includes a tube-shaped adapter unit secured to the snorkel and including a passage; a float unit pivotably secured to the adapter unit and including a projected lever and two upper engagement members (e.g., tabs) at two sides of the lever; a closure unit pivotably secured to the adapter unit and including two mating engagement members (e.g., indents) at both sides, and a closure member adapted to close the passage when the lever pivots upward; and a splash guard secured to the adapter unit for receiving both the float and closure units and including windows for fluid communication. The engagement members are adapted to lockingly engage with the mating engagement members for stopping the closure unit from further pivoting upward and thus preventing the passage from being closed by the closure member undesirably.
