Abstract: This invention relates to an improved socket retainer device for a thin-wall drive portion of a wrench having an inner and outer drive portion. A resilient spring is placed within an elongated slot which is machined in the drive portion of the wrench. The outer edge of the slot is deformed such that the resilient spring is held firmly in place at its ends, the middle portion of the resilient spring being allowed to deflect and frictionally engage sockets when the socket is attached to the drive portion of the wrench. One embodiment of the present invention defines an s-shaped resilient spring and another defines two opposed resilient springs. The design results in lower fabrication and assembly costs and improved socket retention ability without compromising the strength of the drive portion of the wrench.
