<p>The invention relates to a device (1) for the securing and commanded release of an element to be released (7) of a spacecraft, said device comprising a split spool body (2) having at least two spool segments (4), wherein at least one spool segment (4) can be displaced from a first position into a second position, wherein, in the first position, the spool segments (4) hold an end (6) of the element to be released (7) in a holding position and, in the second position, release the end (6) of the element to be released (7) from its holding position, a retaining element (5) for retaining the spool segments (4) in the first position, and a release device (16) for releasing the retaining element (5). The end (6) of the element to be released (7) comprises a rotationally symmetrical, in particular spherical, surface which is bent about two axes and which interacts with counter-surfaces (8), which are bent in such a way, of the spool segments (4) so that the end (6) of the element to be released (7) rests in the first position of the spool segments (4) with its surface on each bent counter-surface (8) by having only a point contact (12).</p> |
