A pipe plug (2, 2', 2'') comprising a shaft (8, 8', 8''); a force transmission body (14) disposed in a rotatable and axially movable manner about the shaft (8, 8', 8'') via a thread connection (16); and a stop body (18). Between the force transmission body (14) and the stop body (18) there is a first compression body (20, 20') disposed in an axially movable manner about the shaft (8, 8', 8'') in proximity of the force transmission body (14); a conical support body (22) disposed in an axially movable manner about the shaft (8, 8', 8''); at least one movable anchoring body (24) on the outside of the support body (22); a second compression body (26) disposed in an axially movable manner about the shaft (8, 8', 8''); and at least one elastic sealing body (28) disposed about the shaft (8, 8', 8''). The shaft (8, 8', 8'') and the first compression body (20, 20') are in direct contact with each other, and the shaft (8, 8', 8'') and the first compression body (20, 20') are connected in a non-rotational manner via complementary connection elements (30', 30''). This prevents the compression body (20, 20') from rotating for optimum transmission and control of an activation force for the plug (2, 2', 2''). |
