ABSTRACT:
A coupler for securing at least one pipe having a planar end. A hollow rigid coupler shell and a rigid tube stiffener are secured in the shell by a hub member, the stiffener having an external diameter less than an internal diameter of the pipe. The hub member has an internal diameter less than an external diameter of the pipe, the hub member having at least one tubular extension which will engage the pipe planar end. The coupler shell has a narrowing internal portion with a separate straight internal portion. At least one hollow follower is provided in the coupler shell straight portion adjacent the hub member tubular extension and at least one flexible hollow boot is movably retained within the coupler shell internal straight and narrowing portions, with a plurality of serrations being provided on an interior surface of the boot. At least one gripper is provided in the coupler shell to prevent the pipe from exiting the coupler shell, whereby the pipe can be positioned within the coupler shell to encompass a portion of the stiffener, the planar end of the pipe abutting the hub and between the hub member tubular extension and the stiffener.
