Abstract
A terminal device such as a terminal post has a retaining portion comprising opposed outwardly formed spring members which are flexible toward each other upon movement of the retaining portion into a hole having a diameter which is less than the maximum transverse dimension of the retention portion so that the terminal device is held in the hole. The retention portion is formed by shearing a blank and displacing material on opposing sides of the shear line in opposite directions parallel to the plane of shearing. Thereafter, the displaced portions are further displaced laterally away from each other and normally of the plane of shearing so that they are separated. Finally, the two displaced portions are formed parallel to the plane of shearing in opposite directions towards each other until they are substantially co-planar.
