Abstract
A method and apparatus for locking a single row of transversely extending parallel tubes. The open end of a U-shaped stake, comprising first and second strip portions elongated in the longitudinal direction with a connecting portion at one end, longitudinally is inserted so as to engage at least the outer surface of a tube located at one end of the row. The stake then is fastened to said row by encircling, in at least one substantially transverse plane, the outer surfaces of each strip portion. The encircling occurs in at least one longitudinal location along said stake that is between adjacent tubes of said row, and locally deforms the stake to further secure the stake against the row of tubes.
