Abstract

A process for producing a hose having a connecting portion includes the steps of a connecting step, and a molding step. In the molding step, a dividable mold is employed in which a first sealing member and a second sealing member are retained so as to form a sealing ring. The sealing ring firmly retains a hose in the mold without pinching and damaging it. Further, the mating surfaces of the first sealing member and the second sealing member are disposed so as to deviate from the center of the sealing ring. Furthermore, a chucking member adapted for locally pressing the hose is disposed adjacent to the sealing ring. Moreover, a recessing portion communicating with the cavity of the mold by way of a narrow passage is formed and the first minimum pressure of the molding material, enabling to pass through the narrow passage, is set less than the sealing pressure exerted between the sealing ring and the hose and is set more than the second minimum pressure thereof, enabling to inhibit the short shot failures.
