<p>A power, motor, or clock spring featuring an integral retainer that prevents the spring from returning to its relaxed state. The integral retainer includes at least two of the coils of the spring being bonded together either through direct bond or via a welding material. The formation of an integral retainer in which the bonded coils of the spring itself acts as the retainer, creates a power spring that is easier and safer to handle and less expensive to create. The bond can be located only at the outermost point of the spring bonding the two outermost coils together adjacent an outer hook of the power spring.</p>
