There is provided an accessory for a writing implement including a body assembly comprising a barrel and a split plug and defining a passage therethrough adapted to receive a pencil. The barrel is provided with an internally threaded end adapted to be engaged by an outer threaded portion of the split plug which is provided with a pair of opposed slots. The respective threaded portions are relatively tapered whereby threaded engagement of the split plug with the barrel causes the slots to close up such that the pencil is retained thereby. The barrel is provided with a pocket clip.
