<p>An apical ring for coupling a conduit of a ventricular assist device to a heart has an annular disk with a central aperture for receiving the conduit. A collar is axially aligned with the central aperture and has a cylindrical shape interrupted by a gap between first and second ends of the collar. The collar has a fixed section joined to the annular disk and has a cantilever section extending from the fixed section to the first end of the collar. A tightener selectively drives the first end toward the second end to close the gap in order to retain the conduit within the collar. The cantilever section includes a relief slot that is expandable for extending a circumferential length of the cantilever section in response to interacting with the conduit when the gap is closed.</p>
