Abstract
A rapid connection coupling for transferring gaseous and/or liquid fluids includes a tubular housing, an outer sliding sleeve and a plurality of locking elements. The outer sliding sleeve is slidably mounted relative to the housing and the locking elements are attached to the housing and movable radially. The locking elements have an engagement profile for connection to a correspondingly formed connection nipple. A sealing piston is centrally slidable in the housing for engagement on the connection nipple, and a spring-biased ring piston is axially displaceable in the housing. The spring piston holds the sealing piston in a retracted position and is displaceably seated relative to the sealing piston.
