Pipe coupling with rapid acting closure

A pipe coupling comprising:

• two clamp halves of essentially C-shaped cross section connected on one end to form an articulated connection such that they are pivotable relative to one another about a bolt, said two clamp halves comprising eyelets and a rapid acting closure for separably connecting the diametrically opposing other ends of the clamp halves, the rapid acting closures comprising a screw bolt, one end of which is coupled to one of the clamp halves and onto the other end of which a screw nut is screwed which tightens the clamp halves into closed position, and a lever lockable in the closed position by means of a first bow-type spring is coupled to the screw nut;
• wherein second bow-type springs are arranged on the side of the pipe in each clamp half eyelets of second bow-type spring being centrally coupled to the articulately connected region of the articulated connection between the clamp halves and the free ends of said second bow-type springs being held in the region of the end of each clamp which is situated on the rapid acting closure such that it can be longitudinally displaced.
