ABSTRACT:
A safety pin having an axially extending coil type torsion spring, thereby avoiding pinching fabric to which it is attached. Alternative embodiments provide arrangements assuring alignment of the wire sections of the safety pin with the head. In one alternative embodiment, the wire sections of the safety pin bend toward the middle of the spring, and enter the head in parallel orientation. In a second embodiment, the head is angled with respect to the coil spring, and the wire sections form a V relative to one another.
