ABSTRACT:
A thin plastic tube or tube connector has at one end section a continuous or interrupted inclined plane means which collapses the plastic tube end section over a nipple or the end of another tube. The plastic tube end section is inserted over the nipple or other tube end to be sealed therewithin by the end wall engaging an O-ring within the end section and held in position by a locking ring drawn over the inclined plane means. The locking ring is drawn over the inclined plane surfaces to uniformly collapse the tube end section into engagement with the nipple or other tube end with a sealing force and with the locking sleeve in frictional locked engagement therewith.
