A system for dynamically sealing an opening through which at least one pipe, cable or duct extends via a conduit sleeve which is fittingly and sealingly fixed to the circumference of the opening or which corresponds to the opening. The system comprises at least an elastically deformable plug which is fittingly and sealingly insertable in the conduit sleeve. The plug has two ends, an outer side and an inner side. Each end has dimensions that allow for fitting of that end in the conduit sleeve. The outer side comprises a number of outer ribs having tops spaced apart in a longitudinal direction of the plug for realising annular contact surfaces between the plug and an inner circumferential wall of the conduit sleeve. The inner side comprises a number of inner ribs having tops spaced apart in the longitudinal direction of the plug for realising annular contact surfaces between the plug and the at least one pipe, cable or duct. The inner side and/or the outer side is provided with at least one hingeable surface area for facilitating compression of the plug in the longitudinal direction and a transverse movement of at least one of the inner or outer ribs.
