In general, this invention relates to a flexible, hinged post or barrier provided with a curved fixed or spring surface serving as the point of contact between the flexible post and vehicle entering a parking space; a hinged support rod used to anchor a return spring between the post to return the post to a vertical position. The rod also incorporates a bolt slot for a locking mechanism consisting of a single lock with dual functional bolt which can lock the flexible post in an upright position and lock the entire apparatus through its foot onto a base plate by the rod penetrating through holes aligned between the foot and base plate. The base plate is secured to the roadway by spikes, anchor bolts, glues or cements.
