Abstract: A shut off valve has a valve lock that snaps onto a cylindric of the valve body and locks the shut-off valve in its open position by retaining the cross bar of a rotatable T-shaped handle in a parallel position in a housing portion of the valve lock. The valve lock also snaps onto the cylindrical end section to retain the cross bar in a perpendicular position at the end of the housing portion to lock the shut-off valve in its closed position.

Abstract: A strap fastener buckle for fastening opposing ends of an object encircling strap includes first and second bridge portions partially defining first and second tubular portions and a deformable retainer extending from the buckle intermediate first and second bridge portions. One end of the strap is initially secured to the buckle. The free end of the strap is then secured to the buckle by passing the free end through first and second tubular portions, folding the free end over second bridge portion, severing the free end at a predetermined point short of the second bridge portion, and securing the severed end between first and second bridge portions by deforming the retainer to a position overlying the severed end of the strap.
