ABSTRACT:
Two clamp members are formed to be fitted around the outer wall of a flexible sleeve when the ends of two pipes are located in the opening of the sleeve with adjacent edges of the two clamp members engaging each other in a clamped position for clamping the sleeve to the ends of the two pipes. Each of the clamp members has two spaced apart clamping ridges extending radially inward from its inner wall continuously between its two edges. The two clamping ridges of the two clamp members are located such that when the two clamp members are located around the outer wall of the sleeve and adjacent edges of the two clamp members engage each other, the two clamping ridges of the two clamp members form two spaced apart clamping ridges extending 360 degrees around the inside walls of the two clamp members for engaging the outside wall of the sleeve forming a seal between the sleeve and the ends of the two pipes when located in the opening of the sleeve. One of the clamp members has arcuate extensions extending from its two edges located and having widths such that the extensions will fit between the two clamping ridges of the other of the clamp members when the two clamp members are located in the clamped position. The clamp members are particularly useful with an industry approved gasket sleeve.
