Claim 3:
4. A tool-less fastening system, comprising:
an interface assembly comprising:
a support including an aperture defined therethrough;
an interface body coupled to the support and having a first longitudinal end, a second longitudinal end, a contact surface disposed between the first longitudinal end and the second longitudinal end, and a stop block extending from the interface body at the second longitudinal end, the stop block including an inclined surface;
a fastening element coupled to the interface body;
a pin extending from the interface body and through the aperture of the support; and
a spring disposed about at least a portion of the pin and positioned between a head of the pin and the support, wherein the spring provides a spring force against the pin and the support operable to draw the interface body in a direction towards the spring and the support; and

a receiver shaped to receive the interface body, the receiver comprising:
a receiver body including a first end, a second end, an upper end, and a lower end, the receiver defining a channel extending from the first end toward the second end, the channel being open at the first end and at least partially open at the lower end extending from the first end toward the second end to define a pin slot, wherein the pin slot is defined between a first interior side wall and a second interior side wall, and the channel receiving the interface body therein with the fastening element and pin extending through the pin slot; and
at least one receiver block extending from the receiver body into the channel, wherein the at least one receiver block includes a receiving surface for receiving the contact surface of the interface body.
