ABSTRACT:
A wrench has a slotted handle for receiving the respective socket members therein. The handle also has at least one window formed therein. The socket members are sized so as to be keyed when disposed in the handle, to prevent lateral and rotational movement therein. The socket members are also provided with a detent engaging member. A detent, carried by the handle engages the detent engaging member so that the socket members so engaged are removably retained in the handle with the socket bore of the endmost positioned member being substantially aligned with the window of the handle.
