Abstract
Abstract A detachable key connector has a socket element and a detachably connectible part which slides into the socket member. The socket member consists of a relatively flat tube having a plate fixed in one end thereof, with the inner edge of the plate formed to provide an undercut recess. A U-shaped spring has its base portion disposed in the undercut recess and includes converging leg portions. The detachably connectible part comprises a flat plate having a bulbous nose portion which snaps releasably between the convergent leg portions of the spring member.
