ABSTRACT:
A device for attaching a hose onto tubing by crimping a sleeve ferrule against the hose and tube stem, the device having a pair of opposing crimper assemblies each having a number of slotted crimper blades aligned to form contiguously abutting blade pairs, where the slots diminish such that the ferrule is deformed as the crimper assemblies are advanced together. The crimper slots terminate in a semi-circular portion so that at the point of full advancement a circle is formed by the opposing slots, resulting in a crimp with no raised longitudinal leak pathways.
