A coupling is disclosed for securing adjacent end web portions without overlap of the webs. The coupling includes series of spaced loops which project endwise from the end portions of the webs and are held in intermeshing relationship by a connector which is threaded through the intermeshing loops and comprises a pair of parallel rods which are freely movable related to one another and convexly curved in cross-sectional profile at least where the rods make contact with each other and which are enclosed in a resilient tube.
