<p>A retaining device especially for holding an articulated manipulator arm on board a spacecraft in its stowed position comprises two relatively linearly movable members, a drive coupled to produce the linear movement, and a grip latter coupled between the members so that, during the driven linear movement, it moves into engagement with a portion of the structure, e.g. the manipulator arm, to be retained and then laterally so as to positively clamp the portion in a fixed position. To hold an articulated structure, several retaining devices all driven by a common actuator can be arranged to grip the structure at appropriate positions.</p> |
