Abstract: An adjustable radiator grill arrangement for a motor vehicle comprises at least one air channel, through which an air flow for the incident flow of a radiator can be guided. The grill arrangement has a first grill element and a second grill element, which are moveable relative to one another, in order to open or to close the air channel. The first grill element comprises a closing edge, which is disposed at a distance from a counter-edge when the air channel is opened and adjacent to the counteredge when the air channel is closed. The first grill element comprises an elastically deformable closing element, which forms the closing edge.

Abstract: The invention relates to a quick coupling for fluid pipes, comprising: a connector with a connecting piece and at least one connecting pipe transversely projecting from said connecting piece, the connecting piece being of the type that can be introduced into a receiving opening of a counterpart in a sealing manner and brought into latching engagement with said counterpart by means of a latching means; a securing means that can be converted from a locking position in which the latching engagement is secured against unlocking to an unlocking position in which the latching engagement can be disengaged; and a fastening means to which said securing means can be fixed in at least one position.
