The invention relates to a PEG probe having a PEG tube (22), an outer holding plate (30), through which the PEG tube (22) is fed and in which the PEG tube is fastened, and a funnel adapter (32), which is associated with an outer end region (26) of the PEG tube (22). A tightly closing valve (34) is arranged either in the PEG tube (22) between the outer holding plate (30) and the outer end region (26) or on the outer end region (26) of the PEG tube (22). The valve (34) blocks the flow through the PEG tube (22) in a closed position and allows said flow at least in the full cross-section of the PEG tube (22) in an open position. The valve (34) has a valve body (46) and a valve housing (36). The valve body (46) is connected to and movable by means of a handle (42) accessible from outside. The valve body is supported in the valve housing (36).
