Abstract: A horizontal connector interconnects adjacent ISO shipping containers. The connector has oppositely disposed locking arms which engage the inside surfaces of the respective container corner fittings. A push block assembly moves in a first direction to rotate the locking arm to engage the inside surface of a corner fitting, and then a reactive force from the surface engagement causes the push block to move in a second direction angularly disposed to the first direction to in turn cause push block surfaces to be frictionally engaged to lock the arm to the corner fitting. This locking action permits the containers to remain securely interconnected even when the connector and containers are subjected to excessive vibrations.

Abstract: Conventionally, a container is secured in the cargo hold of an aircraft by a latch comprising a frame having a floor part to which are attached two upwardly extending side parts.
