Abstract
A cord closure for securely retaining flexible cord, drawstrings, and the like in a selected position includes a plunger member, a compression spring, a retaining ring, and a body housing. There is provided means for initially holding the plunger sub-assembly in a pre-assembled position with the spring being compressed so that the holes of the plunger member and body housing can be readily aligned for insertion of a cord. Once the cord is threaded through the aligned holes, the plunger member is depressed downwardly and released to allow the spring to expand and urge the plunger member to move up axially, thereby locking the cord between the plunger member and the body housing.
