What is claimed as new is as follows:

1. A hair pin comprising a substantially J-shaped primary unit embodying a long limb which is substantially linearly straight, a short limb parallel to but spaced from the long limb and a curvate bight portion joining said limbs together, that portion of said long limb extending beyond the free end of the short limb constituting a first jaw, and an auxiliary unit complemental to said primary unit, and embodying a relatively long approximately straight arm freely hinged between its ends on the free end of said short arm and having an approximate halfportion projecting beyond said free end and opposed to said first jaw and providing a second jaw, the other halfportion being situated and swingable between said short and long limbs and cooperating with the latter and providing a second pair of jaws.

2. The structure defined in claim 1 and wherein that end of the last named half-portion is slotted and slidably engaged with said bight portion.
