This bottom nozzle is of the type comprising a perforated plate to allow water to pass through it, the nozzle having lateral faces (24) and at least one anti-debris element (22) positioned on a lateral face (24) to block out debris likely to infiltrate between the bottom nozzle and another adjacent bottom nozzle. In the free state, the or each anti-debris element (22) permanently projects from the lateral face (24) on which it is positioned, the or each anti-debris element (22) being elastically deformable so that it can contract towards the lateral face (24) in the event of a force being exerted on the anti-debris element (22) towards the lateral face (24). |
