A windscreen for a vehicle, the windscreen comprising a bracket for a sensor including a camera, the bracket being attached to the windscreen and comprising a baseplate and at least one retaining element (30, 32) mounted on the baseplate, wherein the sensor is accommodated within a sensor housing which may be inserted in the bracket, the sensor housing has at least one rod-shaped member (46, 48) projecting from the sensor housing by means of which the sensor housing may be retained in the bracket in a removable manner, and the retaining element (30, 32) comprises a raised bed integrated with the baseplate, characterised in that the retaining element (30, 32) additionally comprises a resilient opposed limb, which is joined to the raised bed at one end and is free at the other end, the resilient opposed limb is positioned in generally opposed relationship to the raised bed, with an elongate space extending between the resilient opposed limb and the raised bed, and the elongate space is closed at one end by the join between the raised bed and the resilient opposed limb, and is open at the other end so that the rod-shaped member (46, 48) may enter the elongate space when the sensor housing is inserted into the bracket and be retained therein, wherein the elongate space widens towards its open end to form a guideway for the rod-shaped member (46, 48), and the guideway guides the rod-shaped member into the elongate space when the sensor housing is inserted into the bracket, and wherein the raised bed comprises a recess to receive part of the at least one rod-shaped member (46, 48), and the resilient opposed limb also comprises a recess to receive another part of the at least one rod-shaped member (46, 48), and preferably the resilient opposed limb is arranged so that the recess provided in the resilient opposed limb is opposite the recess provided in the raised bed, so that the two recesses define together a receiving space for the rod-shaped member (46, 48) within the elongate space, and wherein the receiving space which receives the rod-shaped member (46, 48) is the part of the elongate space where the greatest separation occurs between the resilient opposed limb and the raised bed so that during entry of the rod-shaped member (46, 48) into the guideway, the rod-shaped member comes into contact with the surfaces of the resilient opposed limb and guideway, resulting in the exertion of a force upon them and the deflection of the resilient opposed limb away from the raised bed. wherein the sensor is accommodated within a sensor housing which may be inserted in the bracket, the sensor housing has at least one rod-shaped member (46, 48) projecting from the sensor housing by means of which the sensor housing may be retained in the bracket in a removable manner, and the retaining element (30, 32) comprises a raised bed integrated with the baseplate, characterised in that the retaining element (30, 32) additionally comprises a resilient opposed limb, which is joined to the raised bed at one end and is free at the other end, the resilient opposed limb is positioned in generally opposed relationship to the raised bed, with an elongate space extending between the resilient opposed limb and the raised bed, and the elongate space is closed at one end by the join between the raised bed and the resilient opposed limb, and is open at the other end so that the rod-shaped member (46, 48) may enter the elongate space when the sensor housing is inserted into the bracket and be retained therein, wherein the elongate space widens towards its open end to form a guideway for the rod-shaped member (46, 48), and the guideway guides the rod-shaped member into the elongate space when the sensor housing is inserted into the bracket, and wherein the raised bed comprises a recess to receive part of the at least one rod-shaped member (46, 48), and the resilient opposed limb also comprises a recess to receive another part of the at least one rod-shaped member (46, 48), and preferably the resilient opposed limb is arranged so that the recess provided in the resilient opposed limb is opposite the recess provided in the raised bed, so that the two recesses define together a receiving space for the rod-shaped member (46, 48) within the elongate space, and wherein the receiving space which receives the rod-shaped member (46, 48) is the part of the elongate space where the greatest separation occurs between the resilient opposed limb and the raised bed so that during entry of the rod-shaped member (46, 48) into the guideway, the rod-shaped member comes into contact with the surfaces of the resilient opposed limb and guideway, resulting in the exertion of a force upon them and the deflection of the resilient opposed limb away from the raised bed.
