A latching device, for a vehicle hinge, the latching device comprising: - a mounting hole for mounting the latching device on a pivot shaft of the hinge, - a first abutment surface configured to cooperate with a first knuckle of the hinge, the first knuckle being mounted on the pivot shaft, the first abutment surface thereby rotatably connecting the latching device with the first knuckle about the pivot shaft, and - a latching member, configured to latch with a second knuckle of the hinge, the first knuckle and the second knuckle being pivotably mounted relative to each other via the pivot shaft, between an opening orientation and a closing orientation about this pivot shaft, the latching member being configured so as to be latched with the second knuckle when it is in the opening orientation, in order to thereby rotationally secure the second knuckle and the latching device relative to one another, the latching device being characterised in that: - the latching device is symmetrical with respect to a main plane perpendicular to a mounting axis defined by the mounting hole; - the latching member comprising a latching hook, defining an open contour, being configured to be latched around a latching pin of the second knuckle and comprising: ∘ a cylindrical portion with a circular base, which extends along a latching axis parallel to a mounting axis defined by the mounting hole, the cylindrical portion extending through a main body of the latching device, and ∘ a channel, which radially connects the cylindrical part to an edge of the main body, the channel having a width, measured in a direction orthoradial to the latching axis, which is less than the diameter of the circular base of the cylindrical part; and - the latching device is free of metallic material and comprises a flange which projects from the main body on either side of the main plane, which extends along the cylindrical part and the channel, and which follows a portion of an external contour of the main body about the mounting axis, a second abutment surface being formed along the flange and facing the mounting axis, the first abutment surface, symmetrical to the second abutment surface, being formed on the other side of the plane from the second abutment surface. - a mounting hole for mounting the latching device on a pivot shaft of the hinge, - a first abutment surface configured to cooperate with a first knuckle of the hinge, the first knuckle being mounted on the pivot shaft, the first abutment surface thereby rotatably connecting the latching device with the first knuckle about the pivot shaft, and - a latching member, configured to latch with a second knuckle of the hinge, the first knuckle and the second knuckle being pivotably mounted relative to each other via the pivot shaft, between an opening orientation and a closing orientation about this pivot shaft, the latching member being configured so as to be latched with the second knuckle when it is in the opening orientation, in order to thereby rotationally secure the second knuckle and the latching device relative to one another, - the latching device is symmetrical with respect to a main plane perpendicular to a mounting axis defined by the mounting hole; - the latching member comprising a latching hook, defining an open contour, being configured to be latched around a latching pin of the second knuckle and comprising: ∘ a cylindrical portion with a circular base, which extends along a latching axis parallel to a mounting axis defined by the mounting hole, the cylindrical portion extending through a main body of the latching device, and ∘ a channel, which radially connects the cylindrical part to an edge of the main body, the channel having a width, measured in a direction orthoradial to the latching axis, which is less than the diameter of the circular base of the cylindrical part; and ∘ a cylindrical portion with a circular base, which extends along a latching axis parallel to a mounting axis defined by the mounting hole, the cylindrical portion extending through a main body of the latching device, and ∘ a channel, which radially connects the cylindrical part to an edge of the main body, the channel having a width, measured in a direction orthoradial to the latching axis, which is less than the diameter of the circular base of the cylindrical part; and - the latching device is free of metallic material and comprises a flange which projects from the main body on either side of the main plane, which extends along the cylindrical part and the channel, and which follows a portion of an external contour of the main body about the mounting axis, a second abutment surface being formed along the flange and facing the mounting axis, the first abutment surface, symmetrical to the second abutment surface, being formed on the other side of the plane from the second abutment surface.
