Disclosed is a mechanism for mounting a print head or like device to the shuttle of a printer. The mechanism includes means for securely fastening the print head to the shuttle and is designed to facilitate easy removal and replacement of the print head. The print head includes a cylindrical head section and a generally tapering guide section and has a pair of wedge-shaped locking fins integrally molded on opposite side of the guide sections. In addition, a pair of bosses are molded on the guide section a spaced distance from the locking fins. The shuttle includes a generally upright member having an opening through which the guide section is insertable, and includes two slots whose shape corresponds to that of the molded bosses. The bosses fit into the slots and secure the print head into the proper operating alignment. A releasable retaining assembly is mounted on the shuttle and includes two locking members adapted for clamping engagement with the locking fins. Bias spring means are utilized to urge the locking members into clamping engagement with the locking fins so as to urge the cylindrical head section into tight abutting relationship with the upright member of the shuttle.
