ABSTRACT:
A tape clamp to be fitted into a recess of a hub in a magnetic tape magazine to fix an end of a recording tape to the hub includes a body portion having a curved outer surface, a pair of lugs projecting from the inner surface of the body portion, and a pair of ribs, each rib connecting the free end of a lug and an intermediate point on the inner surface of the body portion. The ribs are inwardly and resiliently deflected when the tape clamp is fitted into the recess. The outer surface of the body portion has an inherent curvature slightly larger than that of the peripheral surface of the hub and is bowed to have a curvature substantially equal to that of the peripheral surface of the hub when the ribs are deflected.
