<p>A blocking device for aquarium filters is designed to prevent the leakage of water and waste material when removing the filter, for example during cleaning operations. The filter (10) consists of one or more filtering bodies (11) in which, in a consecutively aligned direction, there is at least one suction channel (13, 14), and in which the lower part of the internal filter ends with a closing base (15) which forms a chamber in which the flow of water drawn in by the pump (12) reverses its direction. The blocking device also substantially consists of at least one swivel element (19) positioned in correspondence with the passage of the flow of water.</p> |
