Telecommunications enclosure comprising: a casing defining an inner cavity for housing a telecommunications module, a base adapted to be removably coupled to the casing to close the casing, and a plurality of sealing assemblies adapted to be removably coupled to the base, wherein: each sealing assembly of said plurality of sealing assemblies comprises an elastically deformable sealing module, a first member and a second member, the elastically deformable sealing module being interposed between the first member and the second member, and the elastically deformable sealing module, the first member and the second member defining a respective cable port; the first member and second member of each sealing assembly comprise each a main portion (47, 59) and a movable portion (51, 63), wherein the movable portion (51, 63) is movable between an open position, wherein a cable is allowed to access to the elastically deformable sealing module, and a closed position; the elastically deformable sealing module of each sealing assembly has an access to allow the cable to enter the respective cable port when the movable portion of the respective first member and the movable portion of the respective second member are in the open position, the access of each elastically deformable sealing module being commutable between an open condition for entering of the cable into the respective cable port and a closed condition; in the closed position, the movable portion of each first member is coupled to the respective main portion and the movable portion of each second member is coupled to the respective main portion so as to wrap the cable; the elastically deformable sealing module of each sealing assembly is held by the main portion of the first member and by the main portion of the second member of the sealing assembly while the respective movable portion of the first member and the respective movable portion of the second member are in the open position; characterised in that the elastically deformable sealing module of each sealing assembly is configured to hold the cable in the respective cable port while at least one of the respective movable portion of the first member and the respective movable portion of the second member is in the open position; and in that movements of the movable portions (51, 63) of the first member and second member of each sealing assembly between the closed position and the open position do not commutate the access of the respective elastically deformable sealing module into the open position. a casing defining an inner cavity for housing a telecommunications module, a base adapted to be removably coupled to the casing to close the casing, and a plurality of sealing assemblies adapted to be removably coupled to the base, each sealing assembly of said plurality of sealing assemblies comprises an elastically deformable sealing module, a first member and a second member, the elastically deformable sealing module being interposed between the first member and the second member, and the elastically deformable sealing module, the first member and the second member defining a respective cable port;
