Abstract
A thin plastic tube has at the end a continuous or interrupted inclined plane means which collapses the plastic tube end section over a nipple or another tube end. The plastic tube end section is inserted over the nipple or other tube end to be sealed thereby with 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.
