System for dynamically sealing at least one conduit through which a pipe or cable extends

A system for providing a sealed transit for a situation wherein one or a plurality of cables, pipes or ducts extend through the transit, wherein the system comprises a frame which is sealingly fixed or fixable into or onto an opening, wherein the frame comprises a plurality of conduits which are each suitable for receiving at least one of the plurality of cables, pipes or ducts and for receiving an elastically deformable plug for sealingly filling space between an inner circumferential wall of the conduit and the at least one of the plurality of cables, pipes or ducts, wherein the system further comprises at least one elastically deformable plug which is fittingly and sealingly insertable in one of the conduits, wherein the plug has two ends, namely a proximal end and a distal end, and an outer side and an inner side, each end having dimensions which allow for fitting of that end in the conduit, the outer side comprising 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 the inner circumferential wall of the conduit, the inner side comprising a number of inner ribs having tops spaced apart in a longitudinal direction of the plug for realising annular contact surfaces between the plug and the at least one cable pipe or duct extending through the conduit sleeve, wherein 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, wherein the system further comprises at least one blocking element integrally connected to the frame for hindering in each conduit movement downstream a pressure gradient of one end of the plug as inserted in that conduit, so that the plug will be compressed by movement of the proximal end to the distal end.
