A surgical cutting instrument includes a hollow hub that has a working portion which terminates at a working end and a connection portion which terminates at a connection end. The connection portion defines a cavity and a lock member which projects from an outer surface of the connection portion A surgical cutting element extends from the working end and is operationally connected to a source of motion. A hollow hub connector has a cylindrical wall with a hand-piece connection portion and a hub engagement portion The hub engagement portion defines a chamber for receiving the connection portion of the hub The chamber has a longitudinal axis A parallel to the length of the hub connector The hub engagement portion further defines a channel through the cylindrical wall for receiving the lock member The channel is in communication with the chamber and has a longitudinal section defined along the length L of the connector. The channel also has a second transverse section communicating with the longitudinal section at a first end and having a second opposite end Further, the channel has a locking recess defined in the wall perpendicularly to the transverse section and in communication with the opposite end of the transverse section The locking recess is sized to receive the lock member A spring element urges the lock member into the locking recess when the locking member is rotated into the opposite end of the transverse section of the channel
