Abstract
A cable transit includes an outer frame (10), at least one module-based cable seal, and a final seal which fills-out the frame together with the cable seal. The final seal includes two compressible wedges (11, 12) which can be moved towards an away from each other by a screw (17), and two further compressible wedges (15, 16) which can also be moved towards and away from each other and which coact with the two first wedges. The four wedges are held together by a movable strap (19) which holds the wedges so that they can move relative to one another, wherein the wedges and the screw (17) together form a contained component which can be easily fitted into the frame. The outer side of the flexible strap (19) is provided with guide shoulders (191 to 194) approximately opposite the further wedges (15, 16) for guiding the component to a correct position in the frame. The strap and the wedges are molded in one piece, and one end (51) of the strap is glued to the other end (52) thereof.
