An apparatus comprising a plurality of releasably connected modules adapted to be placed on a road surface for arresting the progress of a vehicle. Each module is equipped with a number of blades which can be protruded or retracted to respectively arrest or allow the passage of vehicle thereover. The modules are interconnected in a manner which enables simultaneous actuation of all the blades and compensates for the camber of the road surface or the misalignment of the modules.

Apparatus for selectively arresting the progress of vehicles, comprising: a plurality of releasably connected modules, each module being shaped to lie on a road surface to allow the passage of a vehicle thereover, and having vehicle arresting means moveable between a retracted position inside the module and an operative position in which the arresting means protrudes from the module to prevent progress of the vehicle, the modules being interconnected by an actuating means which enables simultaneous actuation of all the arresting means, the actuating means comprising male and female connectors, each male connector comprising a member adapted to locate in a female connector and including cooperating means such that rotation of the male member causes rotation of the female connector, wherein the female connector comprises a channel into which the male member is received, the channel having a lip portion for preventing axial removal of the male connector and the distance from a base of the channel to the plane of the lip being greater than the depth of at least a portion of the part of the male member which, in situ, is located directly between the lip and base to allow limited axial and/or tilting movement of the male member in the channel.
