Abstract

A locking mechanism for magnetic computer tape to be used in conjunction with a closure strap or canister, the magnetic tape being wound about a central hub of a reel, the reel comprising a pair of spaced circular flanges connected at their centers to the hub; the locking mechanism comprising a flexible plastic strip having double sided adhesive pads attached to its ends, the loop being bent and joined at its adhesive ends to form a small loop; the loop being firmly attached to an interior portion of the strap or canister whereby the loop fits between the flanges and bears against the outer winding of the tape to prevent the tape from becoming unwound.
