The grilled cover piece for drainage channels has a substantially horizontal wall covering the channel and a longitudinal hollow ridge which extends upwards with its top wall having eyelets or holes. The cover piece is positioned flush with or just below the level of the surface from which the water to be drained must be removed, wherein the water flows down by means of gravity into the underlying channel which conveys the water away. The cover piece is provided transversely at one end with at least one female profile and at its other end with at least one male profile complementing the female profile, so that it is possible to connect and fix together several cover pieces arranged in succession so as to cover the channel along the entire length.
