ABSTRACT:
A swickle connector includes a connector body with an inlet end and an outlet end that is adapted for engagement with a sealing member of a sampling device or the like. The outlet end of the connector body includes a central axis. A clamping seat is associated with the connector body and includes an equilibrium point that is coincident with the central axis such that a clamping force acting on the clamping seat extends only in the direction of the central axis to thereby cause substantially uniform sealing engagement of the outlet end with the sealing member.
