A coil of hollow tubing is bonded onto itself to retain the integrity of the coil by depositing a bead or stream of adhesive onto the exterior of the tubing along the extent thereof. By coiling the tubing the adhesive comes into contact with itself to removably bond the coil together. In use, any desired section of the coil is "peeled" from the remainder of the coil. The present invention is particularly advantageous in use with drain tile.
