The devices are intended for attachment and further separation of the objects fixed by one device or by some devices, by way of electric signal supply. The devices can operate at all stages of operation; in this case, the axial and lateral loads are carried in the joint of the objects separated. They have low impulse of force that effects the object separated; devices 00.2601.2001.0000.05.0 and 94.0003.5201.0000.00.0 do not eject the combustion products of the pyroelement and the elements of the locking device into the ambient environment.

This development work solves the problem of reliable fastening of the separated objects at all stages of operation and their separation without any disturbances practically, by an electric signal. Devices 00.2601.2001.0000.05.0 and 94.0003.5201.0000.00.0 do not eject the combustion products of the pyroelement and the elements of the locking device into the ambient environment. The devices are simple in operation, they are of small weight and high reliability P>0.99995 which is verified by experimental development and by practical injection of various objects into the orbit including Uo SAT-12, UniSat, Meg SAT using device 00.2601.-2001.0000.05.0.
