Stabbing guide device for a steel tube designed to be secured on a portion of said tube used in a tubular column for oil and gas, energy, or storage applications, said device comprising: - a substantially cylindrical body extending along a rotational axis designed to surround the portion of the first steel tube, said body forming an open ring so that a circumferential gap subsists between two free ends (33a, 33b) of said body; - a locking door secured in a non-detachable way to the body at one of the two free ends (33a, 33b) of said body, one of the body or the locking door comprising a hinge cooperating with at least one longitudinal shaft connected to the other of the locking door or the body, the locking door being configured to move compared to said body between: • a locked position in which the locking door surrounds the first tube and is blocked in rotation around the longitudinal shaft, the locking door being, in said locking position, able to slide along the rotational axis towards a lower end of the body into an intermediate position, • the intermediate position in which the locking door surrounds the first tube and is able to rotate radially away from the body, and • an unlocked position in which the locking door is radially away from the body, the locking door being configured to rotate along the longitudinal shaft from the intermediate position to the unlocked position. - a substantially cylindrical body extending along a rotational axis designed to surround the portion of the first steel tube, said body forming an open ring so that a circumferential gap subsists between two free ends (33a, 33b) of said body; - a locking door secured in a non-detachable way to the body at one of the two free ends (33a, 33b) of said body, one of the body or the locking door comprising a hinge cooperating with at least one longitudinal shaft connected to the other of the locking door or the body, the locking door being configured to move compared to said body between: • a locked position in which the locking door surrounds the first tube and is blocked in rotation around the longitudinal shaft, the locking door being, in said locking position, able to slide along the rotational axis towards a lower end of the body into an intermediate position, • the intermediate position in which the locking door surrounds the first tube and is able to rotate radially away from the body, and • an unlocked position in which the locking door is radially away from the body, the locking door being configured to rotate along the longitudinal shaft from the intermediate position to the unlocked position. • a locked position in which the locking door surrounds the first tube and is blocked in rotation around the longitudinal shaft, the locking door being, in said locking position, able to slide along the rotational axis towards a lower end of the body into an intermediate position, • the intermediate position in which the locking door surrounds the first tube and is able to rotate radially away from the body, and • an unlocked position in which the locking door is radially away from the body, the locking door being configured to rotate along the longitudinal shaft from the intermediate position to the unlocked position.
