Abstract
The aim is to devise a gas plug connector that permits a gas plug to be connected or disconnected only when an additional shut-off valve has been manually closed. To that end the housing (1) of the gas plug connector has a bearing (36) for a switching element (35) that on the one hand is fitted with a guide device (37), on which one end of a plunger (11; 12) installed in the base (2) of the housing (1) is supported, whereas the other end of the plunger (11: 12) is connected to a valve head (15) of a shut-off valve (8) positioned in the gas-carrying chamber (7) of the base (2). On the other hand, the switching element (35) is connected to a locking device, by means of which an insertion of the gas plug (57) dependent on the position of the switching element (35) can be prevented.
