Abstract
A handwriting instrument consists of a top part (1) and a connected intermediate part (2), on the end of which a tip (3) is fastened. To make it possible to insert the intermediate part (2) into the top part (1) rapidly and securely during the assembly of the handwriting instrument, there are two detent elements (5) and two lead-in bevels (8) on the top part (1), which guide two flexible studs (4) into the detent elements (5), where the studs (4) are locked. A sleeve (11) fastened to the intermediate part (2) by means of a bayonet connection (13, 21; 12, 14, 20) covers the studs (4) and the detent elements (5). For easy handling of the writing instrument, there is a grip (18) made of non-slip butt soft rubber on the intermediate part (2).
