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 (A1) designed to surround the portion of the first steel tube , said body forming an open ring so that a circumferential gap (J1) subsists between two free ends of said body ; - a locking door secured in a non-detachable way to the body at one of the two free ends 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 (A1) 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 (A1) designed to surround the portion of the first steel tube , said body forming an open ring so that a circumferential gap (J1) subsists between two free ends of said body ; - a locking door secured in a non-detachable way to the body at one of the two free ends 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 (A1) 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 (A1) 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. <EOS>
