A tube connection assembly for external filters for aquariums comprising a container that is closed by an upper lid and contains at least one filtering mass crossed by a water stream that is forced by a pump incorporated in the lid; two valves with flow control elements, which are arranged coaxially
A tube connection assembly for external filters for aquariums comprising a container that is closed by an upper lid and contains at least one filtering mass crossed by a water stream that is forced by a pump incorporated in the lid; two valves with flow control elements, which are arranged coaxially and are coupled to each other, a lever-type regulator protruding from a central region of the flow control elements; a lever-type engagement system articulated to the assembly between the regulator and the lid, acting on the same plane as the regulator, and having a wing for engaging the lid for extraction and a wing that allows the release movement by its insertion in a coverable seat that is provided between the flow control elements and is accessible to the wing only when the regulator is in the position that causes the simultaneous closure of the streams.

1. A tube connection assembly for external filters for aquariums, of the type comprising a container that is closed hermetically by an upper lid and contains at least one filtering mass crossed by a water stream that is forced by means of a pump incorporated in said lid, said container being shaped
1. A tube connection assembly for external filters for aquariums, of the type comprising a container that is closed hermetically by an upper lid and contains at least one filtering mass crossed by a water stream that is forced by means of a pump incorporated in said lid, said container being shaped so as to form, in the lid, parallel connectors, respectively for the input and output of the stream, in which said tube connection assembly engages, said tube connection assembly supporting the ends of tubes for connection to an aquarium, said tube connection assembly comprising two valves with cylindrical flow control elements, which are arranged coaxially and are rigidly coupled to each other, a lever-type regulator protruding from a central region of said flow control elements in order to move them simultaneously by rotating the regulator on a plane that is perpendicular to the common axis of rotation, a lever-type engagement system being articulated to said assembly between said regulator and said lid, acting on a same plane as said regulator, and having a wing for engaging said lid and a locking wing that allows the release movement by means of its insertion in a coverable seat that is present between said flow control elements and is accessible to said wing only when said lever-type regulator is in the position that causes the simultaneous closure of the valves. 2. The assembly according to claim 1, wherein said flow control elements are inserted in respective cylindrical seats of the body of said assembly, which are separated by a central region in which a semicircular slot is provided, and have corresponding complementary interlocking ends directed toward the region of said slot. 3. The assembly according to claim 1, wherein said lever-type regulator protrudes from the region of mutual interlocking of said flow control elements, passing through said slot in order to move said elements simultaneously by means of rotations of said regulator on a plane that is perpendicular to the common axis of rotation. 4. The assembly according to claim 3, wherein the end of said regulator designed for coupling to said flow control elements is constituted by a fork with flexible prongs that end with hooks, said end being inserted by flexing through said slot into a through hole formed between said flow control elements, said hooks engaging against the edges of the end that lies opposite the insertion end. 5. The assembly according to claim 1, wherein said lever-type engagement system is articulated to said assembly between said regulator and the region of engagement with said lid, acting on the same plane as said regulator. 6. The assembly according to claim 1, wherein said lever-type engagement system has a hook-like shaped portion that engages a protrusion of said lid, fixing said body to said lid, said engagement being determined by rotations in a direction that determines the greatest angular distance with respect to said regulator. 7. The assembly according to claim 1, wherein said lever-type engagement system has a cantilevered wing for abutting against said lid in order to extract said assembly, said wing being arranged opposite said locking wing and allowing the abutment movement and therefore extraction by means of its insertion in said coverable seat provided between said flow control elements. 8. An external filter for aquariums, comprising an engagement seat for a valve assembly according to claim 1. 9. The external filter for aquariums according to claim 8, wherein in said seat an engagement protrusion is provided for said hook-shaped portion of said lever-type engagement system.
