FIELD: oil, gas and oil industry.
SUBSTANCE: invention relates to field of productive formations in oil, gas and injection wells, namely, to cumulative perforators, by means of which elements charge is fixed in perforator frame and pressing of detonating cord of perforator to charge. Device for installation and fixation of cumulative charge comprises cylindrical casing with channel for fixation and protection of detonating cord, on inner side of which along the entire perimeter wedge-like latches are made, configured to be installed in slots located in upper part of cumulative charge. Outer side of the cylindrical casing in the upper part is equipped with wedge-like petals located opposite to each other with the possibility of installation of the device during its rotation around its axis in the perforator frame.
EFFECT: invention provides simplicity and ease of assembly and reliability of attachment of detonating cord and charge, high efficiency of fixation of charge in frame of perforator, and also enables to fix cumulative charges of different standard sizes.
