Jointing clamp for pressing pipe connections

A jointing clamp for pressing pipe connections, each pipe connection including a pipe having an outer periphery, a supporting sleeve and a pressing sleeve having a terminating end, said jointing clamp comprising:

• connecting plate means including:
• two spaced connecting plates, each of said connecting plate having an outer side, and
• guide plates mounted on said outer sides of said two spaced connecting plates, each of said guide plates having a forked construction with two spaced legs, and a form recess disposed between the spaced legs of each said guide plate, one of said form recesses having a configuration which fits a part of the supporting sleeve of the pipe connection, and the other form recess fits on an outer periphery of said pipe and engages said terminating end of said pressing sleeve as a stop for said pressing sleeve;
• first and second pressure clamps pivotably mounted on said connecting plate means for pivotal movement about parallel pivot axes in opposite directions between open and closed positions, said first and second pressure clamps being disposed between said two spaced connecting plates;
• a first and second form insert carried respectively on said first and second pressure clamps, and a third form insert on said connecting plate means, said first and second form inserts along with said third form insert being in a clamping position operable to press the pipe connection when said first and second pressure clamps are in said closed position, said first and second form inserts being pivotably displaced from said clamping position to a non-clamping position when said first and second pressure clamps are in said open position, said third form insert being disposed in a stationary position on said connecting plate means when said third form insert is in said clamping position and when in said non-clamping position, said third form insert being at least partially disposed between said two spaced connecting plates;
• affixing means for connecting a clamp driving device to said connecting plate means, with the clamp driving device being operable to drive said first and second pressure clamps from said open to said closed position;
• and
• biasing means disposed between said pressure clamps for biasing said pressure clamps toward said closed position.

• first fastening means for detachably and replaceably mounting said first and second form parts on the respective first and second pressure clamps;
• and
• second fastening means for detachably and replaceably fastening said guide plates to said two spaced connecting plates, said third form insert having at least one part disposed between said two spaced connecting plates, said second fastening means engaging said one part of said third form recess to thereby detachably mount said third form insert on said two spaced connecting plates.
