Abstract: A socket tool extension element includes a latching mechanism for automatically securing a socket to a driven stud on one end of the extension simultaneously with the attachment of a wrench drive stud to a socket portion at the opposite end of the extension. A captive latch ball projecting from an opening on one side face of the driven stud is constantly biased to the projected position by one end of a compression spring housed within a latching bore angularly disposed relative the longitudinal axis of the extension element. The other end of the compression spring constantly engages a bearing member which in turn biases against a lock pin slidably disposed within a bore axially extending from the socket portion to the driven stud of the extension element. In an at-rest condition and with a socket attached to the driven stud, the socket is manually attachable and removable from the driven stud and temporarily retained thereupon by the yieldably biased latch ball.
