Abstract: Releasable locking apparatus for locking together adjacent elongated members such as a support post (10) and a drawbar (16) of a vehicle. In one arrangement, first and second mountings in the form of saddles (20 and 28) are adapted to saddle respective elongated support post and drawbar for non-rotational connection thereto. The saddles are connected to respective support post and towbar by a common pin (21) about which they may rotate when disconnected. Overlapped portions (23 and 29) of the saddles abut to provide a non-rotational connection. Releasable security type locking means attached to pin aperture (25) restrains axial movement along the pin. The support post is movable and releasably lockable from a vertically extending support position to a stowed position extending alongside the drawbar.
