ABSTRACT:
The holder is designed for use with piercing instruments such as that disclosed in U.S. Pat. No. 4,164,224. The holder consists of a pair of jaws connected by a flexible bight. Each jaw has a recess at its free end to receive a portion of the piercing instrument. One jaw has a number of opposing protrusions disposed on an inner surface of the jaw. In use, the piercing instrument is inserted between the jaws of the holder. The piercing instrument is thereby securely retained in all three dimensions, so that it cannot be accidentally dislodged from the holder prior to use, such as during packaging, sterilizing or shipping. The holder and instrument are aligned with, for example, an earlobe between the pin and locknut carried by the piercing instrument. As the jaws of the holder are squeezed together, the piercing pin and a receiving locknut are moved toward one another. Further pressure on the legs of the holder releases the piercing pin, suddenly projecting it through the earlobe into engagement with the locknut. As pressure is relaxed, the resilience of the holder's bight moves the jaws apart, leaving the pin and nut secured to the earlobe and the piercing instrument free of the holder for separation from the pin and locknut.
