A wheel-locking device to secure vehicles on transport vehicle platforms, comprising a pivotally mounted stop member arranged to engage and hold the vehicle wheel in its raised position, a telescopic arm with controlled extension and retraction. At the outer end of said arm is pivotally mounted a bow arranged to be applied over the vehicle wheel. The telescopic arm is pivotally mounted at its lower point of attachment and so directed that in its raised position for the purpose of applying said bow over the vehicle wheel, said arm forms an acute angle to a vertical plane extending at right angles to the arm pivot axis through said point of attachment and is positioned on the opposite side of said vertical plane relative to the plane formed by said raised stop member, whereby said wheel will be firmly secured between said bow and said stop member.
