Spring actuated fastening device with width/tension adjustment capacity

A fastening device for bags, luggages and other receptacles comprising:

• a bag/luggage fastening device (10), made of cast metal, or plastic or any other suitable material having an essentially u-shaped body which consists of an arced posterior portion (22) which descends to form two laterally spaced arms (12), said arms carrying two projecting pairs of aligned, opposing, compression spring actuated beveled catches (18) and (20), said catches being smooth and rounded and transversely, moveably mounted and coming together to form restrictive entrants (71) and (73) which can be substantially, laterally depressed, said opposing, spring actuated catch pairs (18) and (20) being so located and positioned that said catch members are held in a locking or opening position with respect to a rigid, engaging depressant, and said lateral arms (12) at their anterior portion forming an introductory opening (70) which, when said fastening device (10) is advanced linearly, allows for engagement with said centrally and correctly located depressant, said spring actuated catch pair (18) is laterally depressed, via entrant (71), allowing for the entrance and registration of said engaging depressant member within the confines of the essentially quadrilateral primary opening (72), and upon a subsequent linear advancement of said fastening device (10) said rigid depressant is able to repeat its depressing action, via entrant (73), against the second pair of opposing spring actuated catches (20), thus allowing for the entrance and registration of said depressant within the confines of the essentially arced secondary opening (74).
