Gas plug connector

A gas plug connector including a housing (1), the housing (1) including a base (2) with an inlet socket (5) to provide a secure connection of the gas plug connector with a fixed gas pipe, an outlet socket (6) for connecting a gas plug (57) and a shut-off device (23) in the base (2), which shut-off device (23) only opens the inner gas path when the gas plug (57) is connected after external tightness has been established, a hood (3) that covers a connection opening (30) of the outlet socket (6) by means of a cover (51) when the gas plug (57) is disconnected, and a base plate (4) that are all interconnected, comprising:

• the housing (1) having a bearing (36) for a switching element (35) fitted with a guide device (37), on which one end of a plunger (11;
• 12), installed in the base (2), is supported, whereas the other end is connected to a valve head (15) of a shut-off valve (8) positioned in a gas-conducting chamber (7) of the base (2) in such a way that the shut-off valve (8) can be brought into its open and closed position via the switching element (35), the switching element (35) being connected to a locking device wherein insertion of the gas plug (57) is prevented when the shut-off valve (8) is in its open position, and wherein insertion of the gas plug (57) is possible when the shut-off valve (8) is in its closed position.
