<p>A connection arrangement for a toilet system having an emptying tube (1) connected to a closed sewage collection tank is described. The emptying tube (1) has an end portion that extends through a wall (5) and has a free end that projects from the wall (5) for reception in a socket of a coupling hose. A cover (6) is attached to the wall (5) and is moveable relative to the wall (5) between an open position, in which the cover (6) allows free access to the free end of the emptying tube (1) for emptying the sewage collection tank, and a closed position, in which the cover (6) protects the free end of the emptying tube (1) against contamination and damage. A plug (101) is attached to the cover (6) and engages the free end of the emptying tube (1) when the cover (6) is in the closed position and is disengaged from the free end of the emptying tube (1) when the cover (6) is moved from the closed position to the open position. When the cover (6) is in its closed position, it defines with the wall (5) a space that is substantially larger than the space occupied by the free end of the emptying tube (1), whereby the free end of the emptying tube (1) is reliably protected from contamination and damage.</p> |
