A rake, in which its tines are inserted and moved between the parallel uniformly spaced, bars of a grating for debris removal. The rake includes a base and plurality of equally spaced parallel tines forming blades intefrally moulded with the base out of a thermoplastic with memory characteristics. The thickness of each blade is about 1/16 its width, each blade is easily flexible thicknesswise, that is in a direction transverse to the grating bars but has practically no flexibility in the direction of the grating bars. The distance between the grating bars is two to four times the rake tines thickness so that at least two rake tines can be inserted between two adjacent grating bars.
