FIELD: construction and repair of underground pipelines. SUBSTANCE: proposed variable-section sealing cup encloses, by its one larger-diameter end, outer surface of end of protective housing, and by its other smaller-diameter end, it encloses outer surface of pipeline. Said cup accommodates variable-section shell enclosing outer surface of end of protective housing and it does not project from cup. Cup and shell are conical, are made of elastic multiplayer material and are secured on end of housing by clamp. Other end of cup is secured by second clamp on pipeline. Cup and shell are either detachable or non-detachable. EFFECT: provision of reliable sealing of end faces of protective housing at centered and non-centered arrangement of pipeline in protective housing. 5 cl, 1 dwg
