A mechanical restraint is provided for use in securing a parked vehicle to a stationary structure, such as a loading dock, while the vehicle is being loaded or unloaded. The restraint includes a first member fixedly mounted on the front wall of the loading dock, and a second member mounted on the first member for movement in a vertical plane and for hinged movement about a vertical axis between operative and inoperative modes. The second member is provided with an elongated first section which is in sliding engagement with the first member. The second member, when in a raised position is adapted to turn about the longitudinal axis of the first section which is coaxial with the hinge axis of the second member. The second member is provided with an elongated second section which projects angularly from the upper end portion of the first section. The second section includes a distal end portion provided with a depending projection. When the second member is in the operative mode, the distal end portion is adapted to overlie and interlock with a transverse bar, such as an ICC bar, which depends from the rear portion of the parked vehicle. The second section of the second member includes a safety element which effects separation of the first and second members only when an external pulling force above a predetermined amount is exerted on the distal end portion of the second section.
