Hygienic process coupling assembly

A hygienic process coupling assembly comprising:

• a retainer having a ring-shaped retainer wall with a first end and a second end, the second end including a flange protruding radially therefrom;
• a plurality of guide rails extending along the flange, the plurality of guide rails including a guide surface extending from a beveled guide step to a stop wall;
• and
• an end cap comprising:
• a head portion comprising a solid transverse wall with a top surface, a bottom surface, and an actuation element engaged with the top surface;
• a plurality of latching arms extending downward;
• and
• a plurality of latching fingers extending inward from the plurality of latching arms, positioned to securably engage the plurality of guide rails of the retainer during a twisting motion imparted on the actuation element.
