1. A structure for mounting a clip for a writing implement which has a barrel extending along a longitudinal axis, comprising:
a fastening member made of plastic material integral with the barrel, having a proximal wall and a distal wall with respect to the longitudinal axis of the barrel, the proximal and distal walls being arranged opposite each other and overall extending in substantially parallel respective planes in order to form between them a recess having an open insertion end; a clip including a fastening portion having a substantially uniform thickness and suitable for mounting in the recess by the open insertion end; wherein at least one of the proximal and distal walls includes a plurality of bosses projecting towards the inside of the recess, at least one first boss among the plurality of bosses has a first apex arranged at a first radial distance with respect to the longitudinal axis of the barrel from the wall from which the first boss projects, the first radial distance being adapted so that the first apex makes contact with the fastening portion, and at least one second boss of the wall from which the first boss projects is arranged between the first boss and the open insertion end, the second boss having a second apex arranged at a second radial distance with respect to the longitudinal axis of the barrel from the wall from which the first boss projects, the second radial distance being less than the first distance, wherein the clip is maintained radially in the fastening member by the first boss. |
