ABSTRACT:
This protective jacket of electrical conductors, tubing or the like has a semi-rigid generally tubular sheet body with male and female seam locking members along opposite lateral edges. A single barb-like hook on the male member engages a complementary pocket in the female member for securely interconnecting the edges and closing the seam. The jacket and seam closing members are integrally extruded and have sufficient stiffness that when the seam is closed, the jacket is in hoop tension.
