Abstract
A safety device allows selective opening or closing of a drain opening of a tank, to render such action more difficult for a child. The device has a body, a plug, a means for restricting axial movement of the plug in a conduit that runs through the body, and, optionally, a tether. The conduit is adapted for engagement in the drain opening. The plug is frictionally engaged in the conduit. The means for restricting axial movement has complementary elements disposed on the plug and on the body, such that, in a first rotational position, the plug is axially retained relative to the conduit and, in a second rotational position, the plug is not restricted from axial movement out of the conduit. The tether attaches to the plug and the body to keep the plug proximate to the body.
