摘要：
The fastener structure comprises at least one main bending strip which defines an aperture for the passage of a clamping bolt for the fastener structure. An elastically yieldable second strip extends transversely of the general direction of the fastener structure and is curved in the direction of the length of the second strip and has its concavity facing the main strip. The two ends of the second bear against the edges of the main strip.
