• Figures 1 to 9 illustrate a pen holder 1 essentially comprising a main body 2 extending in a longitudinal direction 10 between a front end 2a and a rear end 2b, a writing pen 6 and a conduit 7 fixed to the main body 2 near its front end 2a, a rear body 4 connected to the main body 2 near its rear end 2b and a cap 8 for protecting the writing pen 6.
• the rear body 4 comprises a housing 14 extending in a loading direction 12 between a front end 14a and a rear end 14b.
• the housing 14 contains an ink cartridge 8 held by a tab 40.
• the main body 2 comprises two wings 32 extending substantially in the longitudinal direction 12 on either side of the rear body 4.
• the wings 32 are interconnected by a rod 22 '. extending through the rear body 4 along an axis of articulation 20 perpendicular to the longitudinal direction 10 and to the loading direction 12.
• the rod 22 has two flats 24a, 24b extending substantially parallel, so that the rod 22 has a substantially rectangular shape in cross section.
• the rear body 4 is articulated with respect to the main body 2 by a groove 26 in which the rod 22 is movable.
• Said groove 26 comprises two guiding surfaces 26a, 26b extending parallel and on either side of a median plane P containing the hinge axis 20 and parallel to the loading direction 12.
• the guide surfaces 26a, 26b of the groove 26 are closely in contact with the flats 24a, 24b formed on the rod 22, so that the rear body 4 moves relative to the main body 2 only in the median plane P.
• the longitudinal direction 10 and the loading direction 12 are then substantially coaxial.
• the wings 32 extending on either side of the rear body 4 cooperate with flat lateral flanks of the rear body 4 to allow the rear body 4 to translate relative to the main body 2 in the longitudinal direction 10 between the unlocked position and the position of use.
• the rear body 4 is retained in the use position 2 by means of a godron defining a boss 30 projecting from the guide surface 26b.
• this restraint can be overcome by elastic deformation by exerting a force along the longitudinal direction 10 between the rear body 4 and the main body 2.

In proximity to the stop end 36b, the groove 36 has a neck - like constriction 38, so that the groove 36 has a substantially ⁇ - shaped shape near its stop end 36 to hold the cap 18. closed position. In this position, the cap 38 is retained on the main body 2 near the front end 2a through the neck 38 releasably holding the pins 34 at the stop end 36b of the groove 36. the O-ring 44 held on the main body 2 is compressed against the cap 18 to improve the seal between the cap 18 and the main body 2.
• FIGS. 10 to 12 differs essentially from the embodiment illustrated in FIGS. 1 to 9 in that the pins 34 and the cap 18 have been replaced by a polarizer 134 and a godron 137 formed on the main body 102 and a hood 118.
