Easy connect and release seat belt buckle

An easy to connect and release seat belt buckle comprising:

• (a) a plunger section comprising a base, a cylindrical plunger pin mounted to an edge of the base, the plunger pin having a leading end and a diameter which is substantially greater than the thickness of the base, the base suited to be connected to a flexible seat belt;
• (b) a receptacle section comprising a base and a receptacle mounted to the base, the receptacle having a cylindrical bore therein with its diameter closely matching the outer diameter of the plunger pin so that the plunger pin can fit closely into the bore of the receptacle, the receptacle having an entrance end and wherein the wall defining the receptacle flares out from the diameter of the receptacle bore which closely matches the diameter of the plunger pin to a larger diameter at the entrance end to facilitate insertion of the plunger pin into the receptacle bore, the wall of the receptacle having a slot therein extending from the entrance opening to a terminal position and sized to admit the plunger base to allow the plunger pin to be inserted into the bore of the receptacle without interference from the base but the slot being substantially smaller than the diameter of the plunger pin so that the plunger pin cannot be withdrawn through the slot, the receptacle section further including detent means thereon for resiliently urging a detent ball against the surface of the plunger pin when the plunger pin is inserted into the bore of the receptacle to assist in holding the plunger pin in place within the bore of the receptacle, wherein the detent means includes a ball mounted in an opening in the bore of the receptacle and having a diameter which is less than the ball so that the ball is held within the opening normally partially extending into the bore of the receptacle, and a case mounted to the receptacle base with a spring mounted therein in compression to urge the ball outwardly against the opening to protrude into the bore of the receptacle, wherein the ball is forced outwardly against the pressure of the spring when the plunger pin is inserted into the bore of the receptacle, whereby frictional pressure is exerted on the plunger pin by the ball resiliently urged against the surface of the plunger pin.
