An attachment clip system includes an attachment clip with an upper planar member, an extension member protruding from the bottom surface of the upper planar member, at least one lower planar member affixed to and extending from the extension member and disposed a distance from the upper planar member, and a channel defined in the distance between upper planar member and a portion of the surface of the lower planar member. The lower planar member has one or more catch projections disposed on a surface facing away from the upper planar member. The attachment clip is secured to a multilayered surface segment by insertion of the lower planar member into a first opening in an outer layer thereof and engagement of the catch projections with an offset aperture in an inner layer so that a portion of the outer layer is disposed in the channel.

A buckle according to the present invention has two opposing ends that are removably attached to each other using a locking system. On one end of the buckle, the locking system includes two opposing locking pins coupled to a spring that is fully enclosed and protected from external elements. On the other end, corresponding rivets or pin casings with plungers are operable to receive the locking pins and lock the two ends together or push the pins out of the casings to release the buckle. The buckle may also include a plug that is removably attached to the adjustable loop end and allows the central bar of the adjustable loop end to be removed without deforming the central bar. Alternatively, each end of the buckle may include self-aligning tabs that guide the ends of the buckle for fastening and aid in the stability of the buckle.

A buckle and method of assembly is disclosed. The buckle may include one or more plugs attached to the adjustable loop end to secure the central bar in place during use. Alternatively, each end of the buckle may a plurality of overlapping tabs that guide the ends of the buckle for fastening and aid in the stability of the buckle.
