Pipe jointing or closing device
First Claim
1. A device for jointing or closing pipe ends, comprising a substantially rigid tubular body, an elastomeric sleeve located within the body and having at least one end protruding axially from the body;
- a clamping ring with means in at least one circumferential position thereon for tightening said clamping ring around the axial protrusion of the sleeve thus to compress said sleeve and force it into sealing engagement with the external wall surface of a pipe inserted into said sleeve; and
said means engaging a part of the clamping ring and a part of the tubular body for holding the elastomeric sleeve and thus the pipe within said tubular body.

Abstract
A device for jointing or closing pipe ends and comprising a single or double-ended rigid or semi-rigid tubular body (10) adapted to retain and protect a single or double-ended elastomeric sleeve (12) with a resilient annular collar (13) protruding from the body at the or each end. The sleeve (12) surrounds the pipe to be joined or closed, and a clamping ring consisting of a pair of semi-circular segments (14) is closed around the collar (13) with bolts (15) and diametrically opposed wedge-like members (18) which are in sliding engagement with the internal surfaces of the clamping ring segments (14) thus to be forced inwardly together with the latter when the bolts (15) are tightened. This ensures a substantially unform radial compression of the collar (13) around the pipe wall.
