Abstract
The temporary connection of two elements (12, 14) is ensured by U-shaped connecting components (16) held in place by a moving part (18). A pyrotechnic composition (20) is housed between two shoulders (32, 36) situated respectively on the first of the elements (12) and on the moving part. Igniting the pyrotechnic composition (20) causes the moving part (18) to slide over the first element (12). The connecting components (16) are released and the connection between the elements (12, 14) is eliminated without breaking any parts.
