A bellows-type cover (10) into which a clamping member (40) is adapted to be securely integrated to form a pre-assembled unit; a groove-shaped recess nea r one end of the bellows-type cover between first (20) and second (22) retaini ng means adapted to receive the clamping member has a two-tier positioning arrangement (11) with a radially inward, circumferentially extending bottom surface (27) for engagement by the clamping member when fully tightened and with a temporary bottom for the clamping member to provide a releasable self - retaining support for the closed, but not yet fully tightened clamping membe r at a radial distance between the bottom surface and the radially outer limit of the recess.
