Claim:
A connection assembly for connecting a spinal implant rod to a spinal implant bolt, the assembly comprising: a rod connecting member having an opening for receiving a portion of the rod; a first interface element on the rod connecting member; a bolt connecting member having an opening for receiving a portion of the bolt; a second interface element on the bolt connecting member, the first interface element being fixed against rotation relative to the rod connecting member and the second interface element being fixed against rotation relative to the bolt connecting member, the rod connecting and the bolt connecting members rotatably attached about a connection axis, one member opposing the other; interlocking structures on opposing surfaces of the interface elements, such that when the elements are engaged with one another, the interlocking structures prevent rotational movement of the interface elements relative to one another; and a compressible member positioned between the interface elements, the compressible member in its uncompressed state preventing the interlocking structures from engaging.
