This highway device includes a frame and an element (14) for covering the frame, the frame (12) including a peripheral border with two walls delimiting a groove and the covering element being equipped with a projecting peripheral lip (32) engaging in the groove in the frame-covering position. The covering element (14) includes at least one ramp (44) extending between the lip (32) and the internal surface of the element, the ramp or ramps being intended to bear on the end edge of the peripheral border of the frame and thus guiding the covering element during the displacement of the latter with respect to the frame, under the action of a force exerted on the element in a zone opposite the ramp or ramps (44).

1. A highway device, comprising: a frame and a covering element for covering the frame, the frame includes an upstanding peripheral border with two walls delimiting a groove, and the covering element is equipped with a projecting peripheral lip which engages the groove in a frame-covering position, wherein the covering element further includes at least one ramp extending between the lip and an internal surface of the covering element, the at least one ramp being intended to bear on an end edge of the peripheral border of the frame and being operative to guide the covering element, so as to slide and rotate, when the covering element moves in relation to the frame, under an action of a force exerted on the covering element in a zone opposite the at least one ramp, and wherein the at least one ramp is provided on only one side of the covering element. 2. The device according to claim 1, wherein the at least one ramp has a sagittal section in a shape of a sector of a disc. 3. The device according to claim 1, wherein a free end edge of the lip comprises a chamfer constituting a stop for limiting a rotation of the covering element in a direction of opening, in conjunction with a free end zone of an external one of the two walls of the frame, on which an external surface of the covering element butts. 4. The device according to claim 1, wherein the covering element is equipped with grasping means situated opposite the at least one ramp. 5. The device according to claim 4, wherein the grasping means comprise a cutout formed in the external surface of the covering element. 6. The device according to claim 4, wherein the grasping means comprise a through-orifice formed in a wall of the covering element in a zone situated between a border of the covering element and the lip. 7. The device according to claim 6, wherein the lip forms an offset in a zone of said through-orifice. 8. The device according to claim 1, further including a lock for locking the covering element in a closed position, on the frame. 9. The device according to claim 8, wherein the lock includes a pivoting rod secured to a locking bar by means of two end limbs capable of being folded back, the bar being intended to be inserted beneath a stop of the frame. 10. The device according to claim 9, further including a seal interposed between the lock and the covering element. 11. The device according to claim 1, wherein the groove is filled with water and forms, in conjunction with the lip of the covering element, an odour trap. 12. The device according to claim 1, wherein the frame includes, at its base, at least one laterally projecting relief, the lower face of which is provided with a series of ribs for anchoring the device in an embedding material. 13. The device according to claim 1, wherein the frame includes anchoring ribs made in a median part of each side of the frame, the ribs being adapted to oppose bending of the frame. 14. A covering element for closing an inspection shaft or capping a drainage shaft, comprising: a projecting peripheral lip intended to engage in a groove of a support frame, the groove being delimited by a peripheral border of the frame with two walls, wherein the covering element includes at least one ramp extending between the lip and an internal surface of the covering element and being intended to bear on an end edge of the peripheral border of the frame and being operative to guide the covering element, so as to slide and rotate, when the covering element moves in relation to the frame under an action of a force exerted on the element in a zone opposite the at least one ramp, and wherein the at least one ramp is provided on only one side of the covering element.
