Abstract: A coupling for attaching to an end of a tube, pipe, conduit or other round solid or hollow section. The coupling includes an inner body and a collar to be provided around the inner body. The inner body has an interior bore passing through at least a portion thereof to receive a tube and the bore has one or more interior annular protuberances extending into the bore. When the collar is provided around the inner body it applies a circumferential compressive force to deform the inner body such that the one or more annular protuberances engage the tube to seal with it.

Abstract: System for connecting a secondary module to a structure having a port. The system includes a tapping connector attachable to the port, and a primary module attachable to the tapping connector, with the secondary module being mountable on the primary module. A collar is receivable over the tapping connector for supporting the primary module on the structure. The collar is attachable to the tapping connector with the primary module being attachable to the collar. A positioner is supported within the collar for fastening the collar to the tapping connector.
