1. A two-part buckle, comprising:a female buckle part defining a pocket, and including a first strap securing structure;a male buckle part including a forward portion insertable into said pocket and including a second strap securing structure;said female buckle part and said male buckle part defining cooperative releasable locking structure; andspringing structure integral with said buckle parts for moving to absorb load exerted on said locking structure, said male buckle part including a thinned connecting segment between said forward portion and said second strap securing structure allowing deflection of said forward portion relative to said second strap securing structure. 2. A two-part buckle, comprising:a female buckle part defining a pocket and including a first strap securing structure;a male buckle part including a forward portion insertable into said pocket and including a second strap securing structure;said female buckle part and said male buckle part defining cooperative releasable locking structure; andspringing structure integral with said buckle parts for moving to absorb load exerted on said locking structure,said forward portion including first and second spaced arms, each said arm having a distal end adapted for engaging and disengaging said female buckle parts by movement of said distal end, and a brace connected to and between said arms, said brace having a central portion between said arms angling towards said distal ends. 3. The two-part buckle of claim 2, said male buckle part including a thinned connecting segment between said forward portion and said second securing structure allowing deflection of said forward portion relative to said second strap securing structure. 4. The two-part buckle of claim 3, said springing structure including a deflectable bar associated with at least one of said first and second strap securing structures. 5. The two-part buckle of claim 4, said at least one of said first and second strap securing structures including a base bar and said deflectable bar spaced from each other. 6. The two-part buckle of claim 5, said at least one of said first and second strap securing structures including truss support members between said base bar and said deflectable bar. 7. A two-part buckle, comprising:a female buckle part defining a pocket, and including a first strap securing structure;a male buckle part including a forward portion insertable into said pocket and including a second strap securing structure;said female buckle part and said male buckle part defining cooperative releasable locking structure; andspringing structure integral with said buckle parts for moving to absorb load exerted on said locking structure, said springing structure including a bar of one of said strap-securing structures having a deflectable forward edge and a less deflectable portion adjacent said deflectable forward edge. 8. A male buckle part for a two-part buckle having a female buckle part defining a pocket having lateral windows and a slot, said male buckle part comprising;a body;first and second spaced arms extending from said body and adapted and arranged for sliding into and out of the pocket in the female buckle part, said arms having lateral projections received in the windows; anda brace connected to each said arm near said body, said brace extending from one of said arms to the other of said arms and having a central portion angling away from said body between said arms. 9. The male buckle part of claim 8, including a guide pin extending outwardly from said brace, between said arms, arranged with said arms for sliding into the slot in the pocket. 10. The male buckle part of claim 8, including connecting segments between said arms and said body, and an undercut in said connecting segments. 11. The male buckle part of claim 10, said arms disposed at an angle relative to said body, and said undercut disposed on an inside of said angle. 12. The male buckle part of claim 11, including a guide pin e xtending outwardly from said brace, between said arms. 13. A strap securing structure for a device to be held on a strap, said strap securing structure comprising;a deflectable portion about which a strap can be wrapped, adapted for yielding to load applied against said strap securing structure by a strap secured thereto; anda less deflectable portion associated with said deflectable portion, said portions being jointly wrapped by the strap;said portions provided on a single bar by a cavity disposed near an edge of said bar separating said deflectable portion from said less deflectable portion.
