A button system containing two pieces that snap and lock together to fasten multiple articles of clothing. The top piece is made of three distinct parts: a detachable ridged color-coded cover, a fastener that attaches said cover to a rotatable hinged plate, and a fastener that secures all three pieces of the top piece. The bottom piece is also made up of three distinct parts: a plate to receive the hinges from the top piece, a curved structure that connects the hinge/cavity plates to the article of clothing, and a rivet that attaches to the article of clothing and the snap and lock invention.

A detachable button system has a fixed component permanently attached to a garment and a detachable button component. The fixed component a disc-shaped base and a cylinder extending perpendicularly from said base, said cylinder featuring a plurality of tabs projecting perpendicularly from the cylinder and parallel to the base. The detachable portion had an interior cavity for receiving the cylinder, the interior cavity including a plurality of slots corresponding to the plurality of tabs, the slots receiving said tabs. The tabs vary across their width so as to provide a friction fit when the cylinder of the fixed component is inserted into the internal cavity of the detachable component and the detachable component is rotated.

A connecting structure is provided for connecting a first member and a second member, wherein the first member comprises a connecting upright portion and a plurality of locking flanges provided to extend outwards along the circumferential direction of the outer face of the connecting upright portion, while the second member comprises a connecting side-wall portion that overlies the connecting upright portion and a plurality of locking projections provided to extend inwards from the inner face of the connecting side-wall portion. The bottom faces of the locking flanges distend downwards in a convex curved shape and, when the second member is overlaid on the first member and rotated, the upper faces of the locking projections are guided with sliding contact along the convex curved bottom faces of the locking flanges and stopped at the lowermost position of the convex curved bottom faces.

A two-piece tarp fastener device for fastening tarps together includes a male coupler and a female coupler. The male coupler comprises includes a rod that has a first end and a second end. A knob is coupled to the first end of the rod. A pin is positioned in the rod proximate to the second end. The pin has opposing ends that extend from an outer surface of the rod. The female coupler comprises includes a tube that has a first terminus and a second terminus. The tube is hollow and complimentary to the rod. A button is coupled to the first terminus of the tube. A pair of slots, complimentary to the pin, is opposingly positioned in a wall of the tube. The slots extend from the second terminus to proximate to the first terminus. Each slot has a channel that extends transversely from a respective bottom of the slot.

A button including a bottom element which has a stem extending along an axial direction, a closing element which has a pin extending along the axial direction internally to the stem, the pin being configured to bind to the stem, a fixing element having a trunk extending along the axial direction externally to the stem, the trunk being configured to receive and bind to the stem. The stem is configured to be coupled with interference fit internally with the pin and externally with the trunk so that the trunk causes a radial clamping action on the stem and, through the stem, on the pin.
