• a security insert sized to fit on the manhole cover frame and under the manhole cover, said insert having at least one receiving hole in a side of the security insert at a position below the manhole cover frame;
• at least one locking pin, said locking pin fitting within the at least one receiving hole and under the manhole cover frame;
• and
• locking means, to secure the at least one locking pin to the security insert.

A manhole cover security apparatus for use with a manhole cover and a manhole cover frame, said security system comprising:

• a plurality of brackets positioned under the manhole cover frame;
• a security insert sized to fit within the manhole cover frame and sit on the plurality of brackets, said insert having at least one receiving hole;
• at least one locking pin, said locking pin fitting through the at least one receiving hole and under the manhole cover frame;
• and
• at least one locking means, whereby the at least one locking pin may be secured to the security insert by locking the at least one locking pin to the security insert with the locking means.
