A coupling comprising a coupling body (10) having an upper planar surface (11) and a rearward facing slot (12) extending from the periphery of the coupling body (10) for location of a trailer 5 pin, a main latch (17) on the coupling at the end of the slot (12) for releasably securing the trailer pin with respect to the coupling, a pair of housing members (24) having a wall or walls defining an internal passage with a housing member located on opposite sides of the rearward facing slot (12), being spaced from the opening of the rearward facing slot (12) and being aligned with each other, the wall or walls of the housing 10 members being a support surface or surfaces, and a bar (23) slideably arranged to extend through each of the housing members (24) so that a portion of the bar (23) extends across the rearward slot (12), the bar (23) being movable clear of the slot (12) to allow engagement of the trailer pin with the coupling and then inserted into the housing members (24) so that the bar (23) extends across the slot (12) after the trailer pin is coupled to provide a barrier against which the trailer pin can 15 abut to thereby prevent it fully releasing from the coupling should the main latch (17) inadvertently release the trailer pin, the housing members (24) providing support to resist load applied by the bar (23).
