The invention features an elongated strip of resilient material, which strip is secured in and partially surrounds a mounting member, where the resilient strip member has a semi-cylindrical body with a pair of circumferentially facing edge portions. The resilient strip also includes a pair of oppositely disposed, radially-inwardly extending solid, wedge shaped latch members, each extending longitudinally of the latch member and located between one of the edge portions and a point 45 degrees away from the mid-line of the semi-cylindrical body. The mounting member includes a web portion having a pair of oppositely disposed web-latch extensions extending across a chord of the semi-cylindrical body, substantially parallel to a tangent to the circumference of the semi-cylindrical body at its mid-line, and at least one leg member extending from the web portion away from the semi-cylindrical body. A pair of oppositely disposed base members, each extend from a leg member, away from each other and each terminate in a base latch portion. Each of the pair of web latch extensions mates with the semi-cylindrical body adjacent the solid radial latch member, between the latch member and the mid-line of the semi-cylindrical body and each of the pair of base latch portions mates with the semi-cylindrical body adjacent the radial latch member, between the latch member and the closest edge portion.
