Abstract:
1. A connector arrangement that connects a gas conduit to a gas supply device, comprising: a connector attached to the gas conduit, the connector comprising a plurality of spaced retaining tabs; a receptacle formed on the gas supply device and sized to receive the connector and comprising a plurality of receiving slots spaced from each other by a plurality of retaining projections, the receiving slots configured to receive the retaining tabs, and the connector configured to rotate such that the retaining tabs rotate behind the retaining projections to retain the connector within the receptacle; and a visual indicator associated with the receptacle, the visual indicator comprising a visual indicator shroud within the receptacle, the visual indicator shroud configured to rotate with the connector, and the visual indicator shroud having an outer surface, wherein the visual indicator has a first state that provides a visual indication of when the retaining tabs are not rotated behind the retaining projections, and a second state that provides a visual indication of when the retaining tabs are fully rotated behind the retaining projections, wherein rotation of the connector transitions the visual indicator from the first state to the second state, wherein the second state indicates a fluid tight communication is achieved between the gas conduit and the gas supply device, and wherein a first portion of the outer surface of the visual indicator shroud is visible through at least one receiving slot of the receptacle in the first state and is not visible in the second state, and a second portion of the outer surface of the visual indicator shroud, different than the first portion, is visible through the at least one receiving slot of the receptacle in the second state and is not visible in the first state.
