Abstract
A releasable locking device is provided for securing a parked vehicle to an adjacent upright structure. The device includes a first means mounted on the upright structure and a second means mounted on the first means for vertical movement relative thereto between operative and inoperative mode positions. When in an operative mode, the second means is in a raised position and interlockingly engages a portion of the parked vehicle. A third means is provided which releasably retains the second means in an operative mode and prevents accidental movement of the second means from an operative mode position to a lower inoperative mode position. The first means includes guides for restricting movement of the second means to a substantially vertical path.
