Abstract: The elastic loop for securing a bag to a trashcan is an elastic cord formed as an endless loop. The loop may be formed in one-piece, or may be a linear cord with its two ends coupled together to form a continuous loop by, e.g., a coupler crimped about opposing ends of the cord. The elastic cord is constructed of a plurality of elastic strands wrapped tightly in a pliable tubular cover. The continuous loop has a circumference less than the circumference of a trashcan for which it is adapted but can be stretched to fit tightly around the trashcan and thereby secure a trash bag to the trashcan.
