A wide-band compression coupling for flexible hose, piping or tubing is disclosed which has a sleeve assembly extending circumferentially around the adjacent ends of the tube or pipe. The sleeve assembly has an axially extending, radially projecting crown with a unique clamping means at the crown to tighten the sleeve assembly around the ends of the tubes or pipes. The clamping means comprises a pair of opposed spacer members extending axially on each side of the crown and a center member within the crown interposed between the spacer members. The center member is adapted to be forced radially outwardly when the spacer members are drawn together by fastener means. As the center member moves radially outwardly, the sleeve assembly crown is pulled with it to tighten the sleeve assembly around the ends of the tubes or pipes. The coupling is capable of joining together tubes or pipes having unequal outer diameters and can accommodate tubes or pipes within a range of outer diameters.

A compression coupling for fitting around cylindrical objects, which comprises: a sleeve assembly extending circumferentially around the cylindrical objects, the assembly having a crown projecting radially outwardly and extending parallel to the longitudinal axis, a channel being formed within the crown; clamping means at the crown to tighten the sleeve assembly around the cylindrical objects, the clamping means comprising: a pair of opposed spacer members extending axially on each side of the crown, each of the spacer members having an inner camming surface, a center member within the channel of the crown interposed between the spacer members, the center member having a camming surface, the center member adapted to be forced radially outwardly by indirect engagement of the camming surface of the center member by the camming surfaces of the spacer members when the spacer members are drawn together, and fastener means inserted through the spacer members and the crown and positioned radially inwardly of the center member for drawing the spacer members together and for forcing the center members radially outwardly to tighten the sleeve around the cylindrical objects.
