A portable coupler which can detachably fit into opposing corner fittings of adjacent freight containers for joining the containers into an integral unit is disclosed. The coupler includes a unitary tension spindle member shaped at each end to fit into and latch onto a standard container corner fitting. In use, one end of the spindle is fitted into an end opening of the corner fitting of a first container and the spindle is then moved longitudinally to engage and hook into the opening of an opposed end corner fitting of an adjacent container. A pair of bearing rings are fitted about the spindle, each formed with a bearing face to bear against the external face of an opposed container corner fitting. Both bearing rings are engaged to a common outer collar ring that may be manually rotated to separate the bearing rings and simultaneously provide a compression force between the corner fittings of the joined containers and a tension force in the spindle member hooked into both containers. Latch members are slidably mounted on the spindle member with each linked to an opposed bearing ring. Each latch member is engaged into a container corner fitting opening, preventing detachment of the spindle member for the corner fitting in the extended mode.
