A repelling device for winged animals comprising: - a support base, with an elongated shape along a longitudinal axis and comprising a plurality of portions created in an integral body that are distributed one after the other along such longitudinal axis, said support base being provided with a rest lower surface and an opposing free upper surface; - a plurality of repelling elements (50A, 50B, 50C), each of which has a substantially rectilinear base section and two opposite and mutually diverging tips which rise from the base section, said repelling elements being adapted to be associated with the support base so that the tips project upwards from the upper surface of the support base itself; and wherein each portion is provided with: - a housing seat obtained in the lower surface of the support base and adapted to house the base sections of a first repelling element and of a second repelling element arranged mutually transversally and overlapping, with the base section of the first repelling element proximal to the upper surface and the base section of the second repelling element distal from said upper surface, and with - two pairs of slots, each of which extends in a through way from the upper surface of the support base to the housing seat, wherein each pair of slots is associated with a respective repelling element (50A,50B), the tips of which are individually inserted into a respective slot of the corresponding pair of slots, characterised in that each portion comprises a pair of reliefs that extend in height starting from the upper surface of the support base, each relief being placed at a respective slot of the pair of slots associated with the first repelling element and defining an extension of the respective slot itself, making available a rest and contact surface of a portion of the tip inserted into it, said rest and contact surface for the respective tip of the first repelling element being placed at a higher height with respect to the upper surface of the support base, and in that each slot of the pair of slots associated with the second repelling element 50B) is adapted to make available a rest and contact surface for the respective tip, the rest and contact surface for the respective tip of the second repelling element being placed at a height where the upper surface of the support base is placed at the slot. - a support base, with an elongated shape along a longitudinal axis and comprising a plurality of portions created in an integral body that are distributed one after the other along such longitudinal axis, said support base being provided with a rest lower surface and an opposing free upper surface; - a plurality of repelling elements (50A, 50B, 50C), each of which has a substantially rectilinear base section and two opposite and mutually diverging tips which rise from the base section, said repelling elements being adapted to be associated with the support base so that the tips project upwards from the upper surface of the support base itself; - a housing seat obtained in the lower surface of the support base and adapted to house the base sections of a first repelling element and of a second repelling element arranged mutually transversally and overlapping, with the base section of the first repelling element proximal to the upper surface and the base section of the second repelling element distal from said upper surface, and with - two pairs of slots, each of which extends in a through way from the upper surface of the support base to the housing seat, wherein each pair of slots is associated with a respective repelling element (50A,50B), the tips of which are individually inserted into a respective slot of the corresponding pair of slots, characterised in that each portion comprises a pair of reliefs that extend in height starting from the upper surface of the support base, each relief being placed at a respective slot of the pair of slots associated with the first repelling element and defining an extension of the respective slot itself, making available a rest and contact surface of a portion of the tip inserted into it, said rest and contact surface for the respective tip of the first repelling element being placed at a higher height with respect to the upper surface of the support base, and in that each slot of the pair of slots associated with the second repelling element 50B) is adapted to make available a rest and contact surface for the respective tip, the rest and contact surface for the respective tip of the second repelling element being placed at a height where the upper surface of the support base is placed at the slot.
