| 摘要 |
- The invention relates to a device for fastening components, with rapid unlocking. Advantageously, the head (4B) is in the form of at least one radial tooth (4D), the passage (6) formed by the holes (2A, 3A) in the said components (2, 3) exhibits a notch corresponding to the tooth of the elongate element (4), and the latter is produced from a shape-memory alloy with two stable states, it being possible for the tooth (4D) of the said elongate element either to be angularly offset from the said notch and bear against the corresponding component, immobilising the said components with clamping means (5), or to be aligned with the said notch by a torsional deformation of the said element (4) under the action of thermal means (7) detaching the said components. <IMAGE>
