1. A security system for a shipping container of the type having doors with a rotatable keeper bar and operating handle to be secured by a hasp having a pair of ears with vertically-aligned apertures, comprising:

  • a security cover, including;

    a vertical channel having upper and lower ends, a front wall and opposing sidewalls extending rearwardly from the front wall;

    a top plate mounted in the channel, perpendicular to the front and sidewalls and extending rearwardly the extent of the sidewalls;

    a bottom plate mounted in the channel, perpendicular to the front and sidewalls and extending rearwardly the extent of the sidewalls;

    a pair of vertically aligned apertures formed in the top and bottom plates, spaced from the front and sidewalls, for receiving a seal pin therethrough; and

    a pair of horizontally aligned openings formed in the sidewalls, extending forwardly from rearward edges of the sidewalls, for receiving a shipping container handle therethrough;

    a seal pin for use in retaining the security cover on the hasp of the shipping container, including;

    a rigid elongated cylindrical shaft, having upper and lower ends;

    an upper annular groove formed in the shaft spaced from the upper end and extending around a circumference of the shaft;

    a lower annular groove formed in the shaft spaced from the lower end and extending around a circumference of the shaft;

    a pair of end caps for securement to each end of the shaft, each cap having an outward end, an inward end and a central bore extending from the inward end towards the outward end to form a generally cylindrical sidewall with inward and outward surfaces;

    each end cap including an annular groove formed on the inward surface of the sidewall, parallel to the ends and located a distance from the outward end to lie adjacent one of said annular grooves in the shaft when the cap is secured to an end of the shaft; and

    a pair of locking rings for securing each end cap to an end of the shaft, each locking ring having a split toroidal shape, with a diameter such that when the ring is journaled between a pair of associated grooves of an end cap and one end of the shaft it will prevent removal of the end cap from the shaft; and

    a removal tool for removing the seal pin from the security comprising;

    an operable pump mounted within a housing, the housing having upper and lower ends and a sidewall;

    a pump handle connected to the pump and operable to selectively pump up pressure within the pump housing;

    an operable release valve for selectively permitting or preventing the build-up of pressure in the pump upon operation of the pump handle;

    a piston reciprocatingly mounted within a cylinder attached to the lower end of the pump, the piston operable to move downwardly in response to a build up of pressure within the pump;

    a fluid reservoir fluidly connected to the pump, for supplying fluid to be placed under pressure in the pump;

    a punch secured to the piston for movement therewith, the punch having a free lower end;

    a punch housing secured to the lower end of the pump and enclosing the punch therein, said punch housing having a closed lower end with an aperture through which the punch lower end will slide and project upon operation of the pump to move the piston downwardly; and

    means on the lower end of the punch housing for gripping a seal pin end cap and retain the cap in position during operation of the punch to a lower position projecting from the punch housing.
