The device has an active tie rod (10) screwed in a fixed base (4). A retractable tie rod releasing mechanism is formed of clips (11a, 11b) and springs (12a, 12b). The rod is partially made of material with high heat dilation coefficient e.g. aluminum or shape memory alloy, such that the rod is dilated under the action of an internal heater (13) to retract the mechanism and permit shock-free releasing of space appendages (GS). The rod is formed of material layers that modify layers made of material with low heat dilation coefficient e.g. invar(RTM: nickel steel alloy). An independent claim is also included for a method for shock-free releasing of space appendages.
