PURPOSE: To surely hold even a number of hairs on hair elements bundled by attaching a locking part to one end of an upper side member formed with a spirally wound resilient linear member, and bending the linear member while extending the same at the other end so as to be lockable to the locking part.

CONSTITUTION: A resilient linear member such as that made of stainless steel or the like is wound in a spiral form 1a to form an upper side member 1. One end of the upper side member 1 is cut with the dia. of spiral form made relatively larger to form a locking part 2. The other end of the member 1 is made such that the linear member is extended as it is and bent to form a lower side member 3. An end of the member 3 is cut so as to be lockable to the locking part 2. The cut parts of the members 2, 3 are made to have a radius of curvature.
