A lever and latching arrangement having a pair of camming surfaces disposed on one end thereof is attached to one end of a tailstock member of an electronic memory book or central electronic complex book of a computer. This lever arrangement, as rotated about a pivot axis, engages one of the camming surfaces with a portion of the computer frame; the mechanical advantage of the lever system overcomes the large forces required to connect or disconnect the electronic book from the computer connectors. The pivot axis is positioned between the side rail of the book and the computer frame and between the tailstock and the connectors of the book to afford a low profile relative to the tailstock, permitting a more efficient use of available volumetric space within the computer. On the end of the lever distal from the pivot axis, the lever supports a latch which is insertable into a latch-retaining opening in the tailstock of the book, providing the capability to latch the lever in the installed position while not requiring any additional height of the lever structure.
