Abstract: A connection device for use with a blast-resistant container comprises a frame with a recess, and a connecting member. An arcuate surface is formed on the outside of the opening of the recess. The connecting member is connected to the frame at one end with a head engaged in the recess and connected to a side panel at the other end. Thus, this connection device can transmit strong membrane force between each two panels of a container and meet the connection requirement of a blast-resistant container. When there is a blast, the connection device is able to confine the blast within the container in that the maximum strain of the plastic hinge in the connecting member can be controlled by the curvature of that arcuate surface formed on the frame.
