Abstract: The staple has a non-linear bright and two spaced-apart legs depending therefrom. Material weakening means, such as a pair of nicks, is in the regions of the bight adjacent to the legs. When the staple is applied, the legs are bent into a plane approximately parallel to the plane of the bight. When it is desired to remove the staple, the bight is gripped and rotated until it breaks away from the legs.

Abstract: A key holder includes a circular housing including circular base and cover members riveted together centrally thereof and cooperating to define an annular chamber therebetween. Peripheral slots are equiangularly spaced apart around the perimeter of the housing in communication with the chamber, each slot having a narrow portion and an enlarged portion. A retainer clamped between the base and cover members has arms respectively resiliently engaging the cover member for closing the enlarged portions of the slots. Key hooks are respectively associated with the slots, each hook having an enlarged head which passes through the enlarged portion of the slot but not through the narrow portion thereof, the resilient arms of the retainer being deflectable by the key hook head for permitting insertion into and removal from the housing. Visual and tactile indicia are provided on the base member and/or the cover member for respectively designating the slots.
