The claimed invention relates to a pressure sealing means (20) for a cable transit (10). The pressure sealing means (20) comprises two wedge shaped pressure applying elements (21) placed vertically opposite each other with their acute sides facing towards each other and two wedge-shaped tensioning elements (22) placed horizontally with their acute sides facing each other. The pressure sealing means (20) further comprises at least one tensioning member (23) arranged between the two tensioning elements (22). The tensioning member (23) is at least one screw (24) secured in axial direction by a securing means (25) in the pressure applying elements (21) and provided with a right hand thread on one side of the securing means (25) and a left hand thread on the opposite side of the securing means (25).
