Clamping assembly

A clamping assembly, especially for use on a fuel injector of an internal combustion engine, comprising a first component (1) and a second component (2) that is fastenable to, and which has a support surface (20) that is supported against, the first component (1), having an essentially cylindrical outer jacket (21), the second component (2) being clampable via a clamping sleeve (3) that is slid onto the outer jacket (21) and that may be screwed together with the first component (1) and via a snap ring (4) against the first component (1), the snap ring (4) coming to rest against a first clamping shoulder (35), which is formed on the inner wall (33) of the clamping sleeve (3), and against a second clamping shoulder (22), which is formed on the outer jacket (21) of the second component (2).

• wherein the snap ring (4) is configured as a detent that elastically deflects radially, the outer jacket (21) of the second component (2) has an undercut (24), behind the clamping shoulder (22) in the axial direction as viewed looking out from the support surface (20), into which undercut the elastically deflecting snap ring (4) is able to deform radially inwardly so that the clamping sleeve (3), when slid onto outer jacket (21) of the second component (2), is guidable from the support surface (20) out over the snap ring (4), and the snap ring (4), which in the process is pretensioned against the inner wall (33) of the clamping sleeve (3), is able to be forced to snap into engagement in an annular groove (31) that is formed on the inner wall (33) of the clamping sleeve (3) as an opposing detent.
