ABSTRACT A hose clip wherein a flexible annular strap can be placed around one end portion of a hose and a relatively small portion (less than 50 percent) of the inner side of the strap is overlapped by the convex external surface of a deformable insert. The space between the insert and the strap confines one or more springs, or one or more springs are outwardly adjacent the strap, to bias the concave internal surface of the insert against the adjacent portion of the hose. The strap can constitute an endless ring or it can be of finite length and the hose clip then comprises a tightening mechanism for the strap. The insert can be biased by one or more leaf springs, by one or more C-springs or by one or more coil springs. The spring or springs can be caused to store more energy than required to maintain the hose in sealing engagement with a pipe or nipple, and the surplus energy is then dissipated as soon as the strap is placed around the hose and the tubular body is inserted into the hose. At least one end portion of the insert can be connected to the strap, and at least one end portion of the insert is slidable circumferentially of the strap. The resistance of the insert to flexing at least matches the resistance of the strap. The curvature of the internal surface of the insert can approximate or match the curvature of the non-overlapped portion of the inner side of the strap.
