Abstract: A strut includes at least one bridge that provides a defined spacing between first and second frames in a longitudinal direction. At least a first connection portion is disposed on or near an end of the bridge and is resiliently elastically deformable at least in the longitudinal direction. The first connection portion may be press-fit between a base of the first frame and an engaging portion disposed on a flange that extends substantially perpendicular from the frame base. The first connection portion may comprise a base connected to the bridge with at least one inner clip projection having a first connecting member, and an outer clip comprising a base for abutting against a surface of the first frame and at least one outer clip projection extending from the outer clip base. The outer clip projection has a second connecting member that engages the first connecting member.
