Abstract
An indicating cap for a writing instrument has an insert with a blind passage adapted to fit over the tip of e.g. a felt or fiber tip pen or marker and axially movable in a sleeve forming a cap between two limiting positions. One of these positions is defined by a spring detent shoulder against which a shoulder of the insert abuts when the cap is withdrawn from the writing implement. When the cap is thrust properly onto the writing implement the insert is pressed into its second position in which a pin of appropriate color is visible through an end of the sleeve where the projecting pin can be protected by a hood or basket.
