Abstract: The clasp is made up of two main parts - a box-like receptor, and a spring clip inserted into the receptor. The spring clip has a spring finger that has a free end engaging an end wall of the receptor for holding the parts in locked position, and the receptor includes a release member for releasing the spring finger, and thereby releasing the spring clip from locked position and enabling it to be withdrawn. The spring finger has a hump that pushes the release member back to inactive position as the spring finger is being inserted into the receptor, to prevent accidental movement of the spring finger to unlocked position, but the hump acts as a camming surface against which the release member works in the releasing movement.
