Abstract: An assembly includes first and second members connected via a connector that is axially insertable into a channel defined by passages of the first and the second member. The connector exhibits a length extending in a longitudinal direction of the channel and includes first and second expansion blocks, and one or more than one wedge between the first expansion block and the second expansion block, and is configured to be displaced longitudinally relative to the channel to thereby radially expand the connector relative to the channel. At a cross section halfway the length of the connector, a cross sectional area and a height of a first expansion block in a radial direction relative to the channel is smaller than a cross sectional area and a height of a second expansion block in said radial direction relative to said channel. A method of assembling such an assembly.

Abstract: An assembly includes a first and a second member, where the second member has a fork-shaped cross section with a main body and two substantially parallel walls that each comprise at least one through hole and the first member is arranged between the two walls of the second member, having a through hole. The through hole of the first member and the through holes of the second member define a channel. A connector is axially insertable in the channel to an end position and consecutively expandable radially relative to said channel, to connect the first and second member relative to each other. The connector, in an expanded state thereof, pushes the first member against the main body of the second member to define a pre-tensioned connection between the first member and the second member. A method of assembling a first and a second member.
