Claim:
A device for closing an opening, comprising: a frame; a cover articulated relative to the frame around a first horizontal axis by at least one first hinge between an open position and a closed position, the first hinge comprising a first cover knuckle and a cooperating first frame knuckle; a locking device having a locked configuration in which the cover is in a first position relative to the frame and is maintained in a locked-open position, and an unlocked configuration in which the cover is in a second position relative to the frame, wherein the cover is configured to be pivoted around the first axis, wherein the first hinge is configured to permit pivoting of the cover, while bearing on the frame, around a second axis that extends substantially perpendicularly relative to the first axis and horizontally in a mounted condition of the device, and wherein the cover is configured to be moved from the first position relative to the frame toward the second position relative to the frame and vice versa by pivoting the cover around the second axis, wherein the cover is articulated to the frame by a second hinge comprising a second cover knuckle and a corresponding second frame knuckle, and wherein the locking device is formed by the second hinge, which is configured to lock and unlock the cover in its open position by displacement of the second cover knuckle relative to the second frame knuckle in a substantially radial direction relative to the first axis.
