Abstract
A method for connecting a hose with a tubular coupling with a pressure sleeve. The pressure sleeve is crimped at least at two sites separate from one another in the axial direction such that at least two crimp bands extending in the circumferential direction are developed, wherein each crimp band completely caps at least one peripheral groove that is developed on the inner surface of the pressure sleeve. Also disclosed is a method for connecting a hose with a tubular coupling with a pressure sleeve that is crimped at least at three sites separate from one another in the axial direction such that at least three crimp bands extending in the circumferential direction are developed, wherein at least one crimp band completely caps at least one peripheral groove that is developed on the inner surface of the pressure sleeve. Tubular couplings, pressure sleeves and combinations are also provided.
