A tamper resistant seal plug is fitted over a screw head within a recess provided by an upstanding wall surrounding the screw head. The plug is an open ended cup shaped member which is readily insertable open end first into the recess. Removal of the plug for access to the screw head may only be effected through destruction of the plug. The end closure of the plug is breakable to effect its removal and provide an indication of tampering. A distinctive design on the exposed seal plug surface makes duplication impractical. |
