The latch structure is separately manufacturable from the socket structure, and is applied thereto in a separate operation, and is effective to retain the memory module board against inadvertent release from the socket.

In a second aspect, the latch is integrally formed with the socket body, but includes an integral latch lever that may be depressed by application of a downwardly directed force to impose a bending moment on the latch to release the memory module board from the socket.
