A plug connector is provided, in particular for the connection of measuring instruments, which is to be connected to a plug having three flat elongated contact pins, a flat elongated protective contact pin and a threaded hole arranged in its center. The plug connector has a low maximum cross-sectional area and a high tightness. The plug connector has a housing (1) partly forming a cone (11), a hollow cylinder (12) which is molded onto the cone (11) on the side facing away from the plug and has an external thread (121), a nut (5) screwed onto the hollow cylinder (12), and a sealing element (4) which completely fills the hollow cylinder (12) and the nut (5). A four-way cable (3) penetrates the nut (5) and the sealing element (4) in the axial direction. A groove (14) is arranged on the side of the housing (1) facing toward the plug to accommodate a seal (6) and a ring (15) is molded on the cone (11) on the side facing toward the plug and encloses the plug coaxially at the end. A contact insert (2) is arranged in the housing (1), in which four flat contact clamps, to which the ways of the cable (3) are connected, are arranged in a countersunk fashion.
