Abstract: A plug-in connector has a plug member and a locking device for securing the plug member on a counterpart. The locking device has at least one locking element having a release position and a locking position, wherein in the release position the plug member is removable from the counterpart and wherein in the locking position the plug member and the counterpart are locked relative to one another. An actuating element acting on the locking device is provided for moving the at least one locking element from the release position into the locking position in a radial direction relative to a longitudinal axis of the plug member.

Abstract: To cook eggs without eggshells by heat radiation with no risk that the eggs are burnt on their surface by the heat radiation, an egg cooker includes a shield disposed between the egg(s) to be cooked and the heat radiation source and is not connected to the egg(s) to be cooked. Thus, the egg(s) can also be cooked in a form resembling a fried egg. Advantageously, the eggs are cooked in receptacles of a preparation dish, the shield exposing regions of the preparation dish between the receptacles to direct heat radiation. The heat absorbed at the preparation dish can be transmitted to the egg(s) through a heat-conducting connection between the preparation dish and the receptacles to accelerate the cooking process.
