A method for attaching a first surface to a second surface with a fastening device. The fastening device has a female component having a female opening featuring a broader female width at a first depth and a narrower female width at a second depth. The female component also has a female attachment surface with an interior slope rising away from the female opening. The fastening device also has a male component with a male attachment member that at least partially conforms to the interior slope of the female attachment surface. The male attachment member also has a broader male width larger than the narrower female width. The method comprises mounting the female component to the first surface, mounting the male component to the second surface, aligning the male component to the interior slope on the female component and applying pressure to couple the male component and the female component.

A quick release buckle includes a first connecting member, a second connecting member, and a locking member, where the first connecting member is provided with a first chamber, and the second connecting member is provided with a second chamber; the locking member is provided with a first locking part and a second locking part connected to each other; the first locking part is located inside the first chamber, and is connected to the first connecting member through a reset mechanism; and the second locking part is detachably connected to the second chamber.

A retainer apparatus including a first retainer portion, a second retainer portion, and a sensor comprising a motion detector and an alarm. The retainer apparatus includes the first retainer portion configured to be slidably attached to a first harness strap and a second retainer portion configured to be slidably attached to a second harness strap. The first retainer portion is removably attached to the second retainer portion. The motion detector is configured to detect movement of the retainer apparatus and activate the alarm to alert a user in a vehicle if movement of the retainer apparatus is detected.

A buckle includes two coupling modules coupled separably to each other. Each of the coupling modules includes a main unit including a hook member and a coupling member that has a retaining portion, and an operating member having an operating portion and a pushing portion. The hook member of each of the coupling modules is engaged with the retaining portion of the other one of the coupling modules. The operating portions of the operating members of the coupling modules are movable toward each other, during which the pushing portion of each of the coupling modules pushes the hook member of the other one of the coupling modules to disengage said hook member from the retaining portion of the coupling module.
