Abstract: A handle assembly comprises two handle pieces. Each handle piece comprises a left section having left and right ends and inside and outside faces, a right section having left and right ends and inside and outside faces, and a center section containing a notch. The center section connects the right end of the left section to the left end of the right section in a generally diagonal manner. The handle pieces are capable of interlocking such that the center section of each handle piece fits into the notch of the other handle piece, the inside face of the left section of one handle piece is situated against the inside face of the left section of the other handle piece, and the inside face of the right section of one handle piece is situated against the inside face of the right section of the other handle piece. The handle assembly can be incorporated into a bag comprising two handle straps, each handle strap being associated with a different handle piece.
