The wall structure will have an aperture formed therethrough for receiving the rod. The apparatus is assembled by locating the housing and housing spring on one side of the wall structure and the handle and handle spring on the other side of the wall structure with the rod extending through the housing aperture and through the wall aperture with its handle end coupled to the handle and handle spring and its cam located in a holding position to engage the housing such that the cam cannot pass through the housing aperture. Means is provided for preventing the housing from rotating when held next to the wall structure. The handle may be rotated to rotate the rod means to a release position where the cam can pass through the housing aperture. In this position, the housing spring moves the housing and its hasp holding means away from the wall structure for release purposes.
