Writing implement comprising a writing implement sleeve, a spring-loaded writing cartridge, actuated by means of an advancing element, a mechanism made up of a pushing part and catch for arresting the writing cartridge in its disengaged position and a clip, in which the advancing element is formed by a half-shell which surrounds the sleeve over part of its circumference, extends over the greater part of its length, is guided axially movably on the sleeve and is in operative connection with the pushing part of the mechanism. The sleeve has the same diameter over its entire circumference and is provided with two mutually opposite longitudinal grooves, into which two half-shells engage with longitudinally guiding ribs, one of the half-shells being secured against longitudinal displacement on the sleeve and the other half-shell being guided axially movably between two stops. However, the sleeve may also have a different diameter in each case over half its circumference, the half-shell serving as advancing element for the writing cartridge being guided by means of two longitudinal guide ribs in the longitudinal grooves between two stops. |
