Abstract

An improved fitting for releasably connecting a plastic tube to a fluid logic element includes a ring member and a cooperating collet member. The collet member is generally cylindrical with a rigid collar at each end connected by an elastically deformable body section. A throughbore through the collet member includes barbs within the throughbore for gripping a plastic tube inserted in the throughbore. Outwardly extending projections from the middle of the body cooperate with cam surfaces of the ring member as the collet member is inserted into the ring member thereby controlling release of the plastic tube and insuring retention of the tube in the throughbore.
