2. Drain (100) according to claim 1 comprising a filtering element at a first end (31a, 31b) of the conduit (30a, 30b), said first end (31a, 31) being located in the internal volume (25a, 25b) of the hollow body (20a, 20b).

3. Drain (100) according to any one of the preceding claims in which the hollow body (20a) is in the form of a cylindrical part having an internal cylindrical wall (24a), an external cylindrical wall (23a) and a bottom wall (26a) connecting said internal cylindrical wall and said external cylindrical wall, said internal and external cylindrical walls (23a, 24a) and the bottom wall (26a) delimiting the internal volume (25a) of the hollow body (20a), said internal cylindrical wall (26a) delimiting the water outlet (22a), the slide (40a) being arranged in the water outlet (22a) of the hollow body (20a), the slide (40a) being in the form of a hollow part comprising a cylindrical wall (42a), the slide (40a) being arranged in the drain (100) such that: • when in the lowered position, the slide (40a) is arranged so as not to protrude beyond an upper end (27a) of the internal cylindrical wall (24a) of the hollow body (20a), • when in the raised position, the slide (40a) is arranged to extend beyond the upper end (27a) of the internal cylindrical wall (24a) of the hollow body (20a),the cylindrical wall (42a) of the slide (40a) forming an extension of the internal cylindrical wall (24a) of the hollow body (20a).

4. Drain (100) according to claim 3 comprising a bell (80a) positioned astride the internal cylindrical wall (24a) of the hollow body (20a), the bell (80a) comprising a cylindrical wall (81a) and an upper wall (82a), the bell (80a) being arranged partly in the hollow body (20a) such that a lower end (83a) of its cylindrical wall (81a) is opposite, at a distance from, the bottom wall (26a) of the hollow body (20a).

5. Drain (100) according to claim 4 wherein the bell (80a) comprises the conduit (30a).

6. Drain (100) according to any one of claims 1 or 5 comprising a cable (60a) connected to the slider (40a), said cable being integrated into a sheath, said cable being configured to drive the slider (40a) in translation, said cable being intended to be connected to a control element.

7. Drain (100) according to any one of claims 1 or 2 wherein the slider (40b) is arranged partly within the internal volume (25b) of the hollow body (20b), and comprises a lower end (43b) and an upper end (44b), said slider comprising, at its lower end (43b), a valve (49b), and said slide being arranged in the drain (100) so that: • when in the upper position, the valve (49b) blocks the water outlet (22b) from the hollow body (20b), • when in the lower position, the valve (49b) does not block the water outlet (22b) from the hollow body (20b).

8. Drain (100) according to the preceding claim, in which the slider (40b) comprises an internal longitudinal channel (47b), opening at its two ends (43b, 44b), forming the overflow orifice (41b) of the slider (40b).
