Abstract
Abstract A medical instrument is assembled by inserting a mating portion of a first tubular member of flexible resin having a Shore D hardness of 45 or lower into a mating portion of a second tubular member of flexible resin having a Shore D hardness of 45 or lower. The mating portions are joined with a curable, preferaly UV curable, adhesive which shows a Shore D hardness of 70 or lower after curing, thereby forming a firm bond.
