Abstract
A clip for a writing instrument has an external biasing mechanism separate from the connection of the clip to the writing instrument to avoid permanent deformation or breaking of the clip arm and wear on the writing instrument body. The biasing mechanism is a coil spring mounted on the clip arm between two supports for compression and flexion when the clip arm is pulled away from the side of the writing instrument.
