Abstract
A locking device is adapted for releasably locking a seat post relative to a seat tube of a bicycle frame, and includes a tubular body with a lower surrounding member to be secured to the seat tube. An upper surrounding member extends upwardly to terminate at an upper surrounding edge, and has an accommodating space for the seat post, and a slit extending downwardly from the upper surrounding edge. A plurality of protuberances are disposed on and project radially and inwardly of an inner surrounding wall surface of the upper surrounding member, and are angularly displaced from each other. Right and left jaw members are respectively attached on the upper surrounding member, and are moved by a tightening member toward each other to narrow the slit so as to bring the protuberances to abut against the seat post.
