Abstract: A latching device is disclosed herein for releasably securing the components of a plugable electrical connector together to prevent inadvertent decoupling therebetween. The device includes a semicircular base attached to a support about one component of plugable connector while pivotally mounting a latch arm at one end. The opposite end of the latch arm is provided with a closure opening for cooperating with a closure latch projecting from the underside of a lug carried on the base in fixed spaced apart relationship with respect to the latch arm pivot connection with the base. When latched, the arm bears against the other component of the plugable connector so that the other component is fixedly held in connection with the first mentioned component of the connector.
