FIELD: transport.
SUBSTANCE: invention relates to appliances intended for separation of space object or rocket components. Proposed device comprises hosing 1 and dressing block 2 with flat working surface. Channel 19 to accommodate pyrotechnical appliance 3 and piston 18 with blade 3 is arranged in sais housing. Said blade has sharp edge 20 with two lateral parts 21, 22, parallel to dressing block surface. Said lateral parts have sharp edges perpendicular to dressing block surface. Blade 4 is rigidly coupled with piston 18 in its central part. Tear-off elements intended for locking the device in initial position are made up of two cotter pins 5 fitted in the housing and two lateral parts of the blade. Dressing block has two bores 16 to receive lateral parts 21, 22. Channel 19 and piston 18 are cylindrical. Surface of piston 18has grooves 12 to receive O-rings 23.
EFFECT: reliable tearing off and preventing twisting of communication lines in separation.
