A pair of connectors includes first and second connectors. The first connector includes a first assembling surface that contacts the second connector. The second connector includes a second assembling surface that contacts the first assembling surface. The first connector includes a first overhanging portion, which overhangs outward from the second assembling surface in an assembled state of the first and second connectors, and a first projecting portion, which projects from the first overhanging portion beyond a location of the first assembling surface toward the second connector side in the assembled state. The second connector includes a second overhanging portion, which overhangs outward from the first assembling surface in the assembled state, and a second projecting portion, which projects from the second overhanging portion beyond a location of the second assembling surface toward the first connector side in the assembled state.

A fitting includes a hollow main body including a flange that extends radially outward with respect to a central longitudinal axis of the hollow main body and that extends circumferentially 360 degrees around the central longitudinal axis of the hollow main body, a gasket having a cross-sectional shape comprising a pentagon, the gasket positioned on an interior surface of the hollow main body, an end ring coupled to an exterior surface of the hollow main body, the end ring including a flange that extends longitudinally with respect to the central longitudinal axis of the hollow main body, wherein the exterior surface extends at an oblique angle with respect to the interior surface, and a plurality of hooks cach coupled to the gasket and to the end ring such that rotation of the end ring with respect to the hollow main body about the central longitudinal axis of the hollow main body draws the gasket axially with respect to the central longitudinal axis of the hollow main body and radially inward with respect to the central longitudinal axis of the hollow main body, thereby forcing the gasket into a scaling configuration.

The invention relates to a press seal (1) for building up a sealing closure of a through-opening intersected by a line, having an elastomer body (2), a press plate (3a) and a tensioning bolt (4) intersecting the elastomer body (2), wherein the press plate (3a) can be pressed by said tensioning bolt (4) onto said elastomer body (2); the tensioning bolt (4) is screwed into a nut (20) around a rotational axis (21), a section (20a) of said nut (20), which section (20a) lies proximal to said elastomer body (2), being held by a form-fit in a recess in said press plate (3a) and being secured against a rotational movement around said rotational axis (21) thus, a section (20b) of said nut (20), which section 20b lies distal to said elastomer body (2), comprising a flange which protrudes beyond said recess in directions perpendicular to said rotational axis (21) outwards for transferring a force onto said press plate (3a) and pressing said press plate (3a) onto said elastomer body (2) when said tensioning bolt (4) is tensioned.
