wherein lateral supports are connected by at least two cross members, each cross member having two ends, each end extending through a bore in one of the lateral supports, each end of each cross member having an enlarged head portion securing the cross member in the lateral support so that each lateral support has at least two head portions protruding from an external side of the support, and

wherein each cushion member is molded over at least enlarged head portion on the external side of its respective lateral support.

9. The fastener of claim 8, wherein the cushion members have concavities for receiving the head portions of the cross members on the external side of its respective lateral support.

10. The fastener of claim 8, wherein the cushion members have a height that prevents the gripping mechanism from contacting an adjacent surface during normal operation of the gripping mechanism.

11. A strap fastener comprising a buckle including two rigid lateral supports, a gripping mechanism secured between the supports, and each support having an elastomeric cushion member that at least partially encases the support and prevents the support from contacting a surface adjacent the fastener without obstructing accessibility to the gripping mechanism, and wherein the gripping mechanism includes a cam lever that pivots around a pivot pin spanning the lateral supports.

12. The fastener of claim 11, wherein the cam lever has an elastomer-covered end portion.

13. The fastener of claim 11, wherein the cam lever has a front face with teeth for gripping a strap.

14. The fastener of claim 13, wherein the buckle has a front cross member with teeth that cooperate with the teeth on the front face of the cam lever to bite a strap.

15. The fastener of claim 13, wherein the cam lever is spring biased toward engaging the strap.

16. A strap fastener comprising

a buckle having a pair of rigid side supports connected by at least one cross member and a pivot pin, and a spring-biased cam lever that pivots around the pivot pin between gripping and non-gripping positions, and

each side support having a cushion member over-molded on the side support.

17. The fastener of claim 16, wherein each side support includes a plate.

18. The fastener of claim 16, wherein the cross member has two ends, each end extending through a bore in one of the side supports, each end of the cross member having an enlarged head portion securing the cross member to the side support.

19. The fastener of claim 16, wherein the cushion members are connected by a bridge portion.

20. The fastener of claim 16, wherein the cushion members prevent rigid portions of the buckle from contacting an adjacent surface without obstructing easy manipulative access to the cam lever.

21. The fastener of claim 16, wherein the cam lever has an elastomer-covered end portion.

22. The fastener of claim 16, wherein the cam lever has a front face with teeth for gripping the strap.

23. The fastener of claim 22, wherein the buckle has a front cross member with teeth that cooperate with the teeth on the front face of the cam lever to bite a strap.

24. The fastener of claim 16, wherein each side support has an auxiliary plate member, the respective cushion member being molded over the auxiliary plate member.

25. A strap fastener comprising

a buckle having a pair of rigid side supports connected by at least two cross members, each side support having an auxiliary plate structure, and an elastomeric cushion member molded over the plate structure so that the rigid side supports are prevented from contacting an adjacent contact surface.

26. The fastener of claim 25, wherein each side support includes a plate.

27. The fastener of claim 25, wherein the cushion members are connected by a bridge portion.

28. The fastener of claim 25, wherein the buckle includes a gripping mechanism having a pivot pin, and a spring-biased cam lever that pivots around the pivot pin between gripping and non-gripping positions.

29. The fastener of claim 25, wherein each cross member has two ends, each end extending through a bore in one of the side supports, each end of the cross member having an enlarged head portion securing the cross member in the side support so that each side support has at least two head portions protruding from an external side of the support.

30. The fastener of claim 29, wherein the enlarged head portions are rivets.

31. The fastener of claim 29, wherein each cushion member is molded over at least one enlarged head portion on the external side of its respective side support.

32. The fastener of claim 29, wherein the cushion members have concavities for receiving the head portions of the cross members.

33. The fastener of claim 28, wherein the cushion members have a height that prevents the gripping mechanism from contacting an adjacent surface during normal operation of the gripping mechanism.

34. A strap fastener comprising

a buckle having a pair of rigid side members, and a strap gripping mechanism between the side plates, each side plate having an over-molded cushion that prevents the side plates and gripping mechanism from contacting an adjacent surface, and
