Patent ID: 7789431

Claim:
A pipe coupling for use with a pipe including a pipe end, the pipe coupling comprising: an annular sleeve having at least one insertion end shaped such that the pipe end can be inserted and received therein by being inserted in an insertion direction, said sleeve being provided with a projecting flange having an end face tapering radially inwardly in the insertion direction of the pipe, an annular gripping means having a gripping face that will face the outer face of the pipe when the pipe is inserted, an annular resilient sealing means provided axially between the flange and the gripping means, an annular pressure means, and tightening means comprised of bolts, the tightening means attached to the pressure means, the tightening means forcing the sleeve and the pressure means towards each other so as to move the gripping face of the gripping means and the sealing means inwards into tight-gripping and sealing engagement, respectively, with the outer face of the pipe when the pipe is inserted, wherein the pressure means is divided into a number of separate ring segments and is provided with an abutment face that displaceably abuts the end face of the flange and shaped such that by axially displacing the pressure means in relation to the flange the segments of the pressure means are moved inwardly towards the outer face of the pipe when the pipe is inserted, that the bolts extend through elongated, radially extending openings in the flange and that means are provided to substantially retain the bolts radially in relation to the pressure means so that simultaneously with the inward movement of the ring segments of the pressure means the bolts are moved radially inwards.
