A separation device for separating parts along a seam includes a frangible structure and a pressure tube assembly within the frangible structure. The pressure tube assembly includes a pressure tube which contains an explosive detonation assembly/cord that can be initiated to expand the pressure tube, and break the frangible structure with a shock force. The pressure tube assembly also includes a explosive manifold that is recessed in the frangible structure, not protruding from an outer surface of the frangible structure. The explosive manifold receives the ends of the pressure tube, and includes a detonator for detonating the explosive detonation assembly/cord. The explosive manifold has circular-cross-section fittings for accepting a circular ends of the pressure tube. By not having any part of the pressure tube assembly protrude from the frangible structure, improved performance may be achieved. Having circular fittings also improves the seal between the pressure tube and the explosive manifold.
