ABSTRACT OF THE DISCLOSURE A retractable ball point pen includes a barrel which houses a replaceable ball point cartridge which is slidably pre- tractable and retractable and spring biased to a retractable position. A follower bears on the cartridge inner end and a clip member includes a bracket project through an upper slot in the barrel and having opposing inclined slots slidably and swingably engaging pivot projections on the upper faces of the follower. The lower end for the clip member includes a cam sur- face which engages the follower so that inward pressure on the follower lowers it to protract and latch the cartridge and the clip is provided with an arm projecting above the bracket and pressure on the arm swings the cam outwardly to release the follower and cartridge to their retracted positions.
