Abstract
An improved closure member is provided for sealing the open end of a pipe and which is particularly suited for a plastic pipe system. The closure member comprises a tubular cylindrical body closed at one end and which is insertable into the open end of a pipe. An O-ring around the closure member engages the inner periphery of the pipe and fluidly seals the closure member to the pipe while an enlarged diameter flange at the outer end of the closure member abuts against the open end of the pipe in order to prevent over insertion of the closure member into the pipe. At least one and preferably two axially extending channels are formed along the outer periphery of the closure member which are open to the outer end of the closure member through the enlarged diameter flange. Threaded fasteners are then screwed into the flange opening of the closure member and are dimensioned so that the threads embed into both the closure member about its axially extending channel and also into the inner periphery of the pipe in order to securely, but detachably, fasten the closure member to the pipe.
