ABSTRACT:
An improved resilient retainer which provides a highly reliable clamping action upon grooved clevis pins and the like. The pinless retainer configuration comprises two essential sections; a clamping section which is spring loaded to be secured around the core diameter of a grooved clevis pin together with an entry section which prevents the retainer from being removed easily. The retainer requires a grooved clevis pin and the like to be inserted past a first entry section and then snapped into the clamping section. The retainer may be formed from any resilient material and operates effectively with a minimum of insertion force without sacrifice of positive clamping effectiveness. In a second form the pinless retainer includes an encompassing guard clip for the entry section with removal from a grooved pin requiring a first removal of the associated guard clip.
