Writing implement with hinged clip

A writing implement comprising:

• a tubular body element extending longitudinally along a central axis and having an outer surface, and
• a clip comprising an arm extending substantially parallel to the central axis, between a front end and a back end, near which a first and a second flange extend towards the body element, the flanges being mounted on a pivot axis in a direction perpendicular to the central axis, and around which the clip pivots between a closed position in which the arm comes in contact with the implement, and an open position,
• wherein the outer surface of the body element has a first and a second sunken region, one on each side of a first longitudinal plane passing through the central axis, and from which protrude a first pin and a second pin, both extending collinear to the pivot axis,
• wherein each of the first and second flanges has a portion located in the first and second sunken regions and comprises a housing in which the corresponding pin pivots, and
• wherein the portion of the first and second flanges arranged in the first and second sunken regions is of a thickness substantially equal to the depth of these regions, the depth of a region being measured between the bottom of the region and the volume of the outer surface of the body element, and each of the first and second pins has a free end within the volume of the outer surface, and tangential to this volume.
