A drawbolt for the mating shells of a container has a latch whose spaced side walls are provided with open slots that receive a transverse cross-bar on one end of a loop whose other end is engageable behind a hasp on one of the shells. Outwardly directed lugs on the side walls are received in aligned apertures in spaced guide walls of a frame, such walls having edges defining aligned peripheral cam surfaces which, together with the closed end of the slots in the latch, capture the cross-bar of the loop and establish a pivotal connection between the latch and the loop. By attaching the frame to a plate adapted to be mounted on the other of the shells, the apertures in the guide walls are closed by the plate. The free ends of a pair of upstanding tabs on the plate cooperate with the closed ends of the apertures in capturing the lugs on the latch thus establishing a pivotal connection between the latch and the frame. Pivotal movement of the latch on the frame causes the cross-bar of the loop to follow an arcuate path defined by the cam surfaces of the guide walls of the frame allowing the closed end of the loop to be drawn behind the hasp to releasably fasten together the two shells of the container.

A drawbolt comprising: a latch having a pair of spaced side walls; each side wall having an edge, a longitudinally directed slot, one end of which is closed and the other end of which opens at said edge, and an outwardly extending lug, the slots in the sidewalls being aligned and the lugs being aligned; a loop member having a cross-bar received in the slots in the latch, the length of the bar exceeding the spacing between the side walls of the latch; frame means having a pair of guide walls spaced from each other less than the length of said cross-bar; each guide wall having a longitudinal mounting edge, an aperture that opens at the last mentioned edge, and a curved peripheral cam edge, the apertures in the guide walls being aligned and the cam edges being aligned; the latch being located with its side walls adjacent the respective guide walls of the frame means with the lugs received in the respective apertures of the frame means for effecting pivotal movement of the latch on the frame means; and the bar of loop member being trapped between the cam edges of the guide walls of the frame means and the closed ends of the slots in the side walls of the latch for causing the bar to be constrained to move in a curved path in response to pivotal movement of the latch.
