Abstract
The present invention relates to an apparatus which forms a sealed joint between two pipes, particularly but not limited to roofing drain pipes. This apparatus includes a cylindrical body made of rubber or similar material that grips and seals two pipes when it is axially compressed by two halves of an articulated housing as they move towards each other. The two half bodies of the articulated housing are threaded to each other such that when one body is rotated in one direction, the bodies move towards each other, thereby reducing the overall length of the housing, and compressing/deforming the rubber seal.
