Abstract: Filler adapter for unrestricted connecting between a tank, such as bottled gas, and a hose. A sleeve with a "T"-handle distant from an end connection aligns over a central tube for attachment to the tank and to which a hose is attached at the other end. The "T"-handle is rotated to join the hose and the central tube securely to the tank valve without interference from the tank handle and tank protecting members and without the aid of wrenches or other tightening devices. An alternative embodiment includes a device with an angled and curved central tube.
