Patent ID: 7040667

Claim:
A clamping assembly comprising: a first component; a second component fastenable to the first component, the second component including a support surface for supporting against the first component, an essentially cylindrical outer jacket, and a second clamping shoulder formed on the outer jacket, the outer jacket including an undercut behind the second clamping shoulder in an axial direction as viewed looking out from the support surface; a clamping sleeve to clamp the second component against the first component, the clamping sleeve being slidable onto the outer jacket and being screwed together with the first component, the clamping sleeve including an inner wall having a first clamping shoulder and an annular groove formed on the inner wall; and a snap ring to assist in clamping the second component against the first component, the snap ring being a detent to elastically deflect radially and being snappable into engagement in the annular groove that acts as an opposing detent, the snap ring being pretensioned against the inner wall and deformable radially inward into the undercut so that the clamping sleeve, when slid onto the outer jacket, is guidable from the support surface out over the snap ring, the snap ring resting against the first clamping shoulder and the second clamping shoulder when fitted; wherein the clamping assembly is arranged on a fuel injector of an internal combustion engine.
