An apparatus (1) for reliably blocking a vehicle (2) at a loading dock (3) comprises a telescopic arm (4) that at one end (4A) is supported so as to be stationary but is pivotal about two axes (P1, P2) and that at the opposite e nd (4B) is provided with an engagement means (5) for effecting a blocking connection between the vehicle and the area of a loading dock. At the same time as the stationary end maybe provided at a safe position where it is practically completely out of the way when it comes to e.g. snow clearance a nd risk of being run into, the capability of pivotal movement and the telescopi c design of the arm makes it possible to easily maneuver the engagement means into a blocking or restraining engagement from the outside of the vehicle.</ SDOAB>
