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.

The invention relates to a method for producing a hose connection (1) with pressure measuring point for a pressure sensor through a closed wall (3).

A hose assembly, preferably a garden hose assembly, including a jacketed tube that is lightweight, durable and versatile. The tube is able to expand longitudinally along the length-wise axis of the hose between hose ends, as well as radially or circumferentially, to an expanded state in response to application of at least a minimum fluid pressure to an inner tube of the hose. Once the fluid pressure falls below the minimum fluid pressure, the hose assembly will contract. The two layer construction of the hose assembly allows for storage in relatively compact spaces, similar flow rates, approximately one-half the weight, and improved maneuverability when compared to conventional hose constructions. In one embodiment the jacket is formed around the tube in a continuous process that welds a material, preferably using hot air, into the jacket. The welded joint forms a region of jacket that is preferably about twice the thickness of the rest of the jacket. This thicker region results in a stiffer section of jacket that makes the hose more controllable and consistent in use.

An integral hose anti-collapse rib comprises a unitary body having a first cantilevered portion curved in a first direction. This first cantilevered portion defines a first end. A second cantilevered portion is curved in a direction opposite the direction of the first cantilevered portion, in a direction facing the first cantilevered portion. The second cantilevered portion also defines a second end disposed at an opposite extent of the rib from the first end. The hose anti-collapse rib also comprises a locking mechanism that locks the first end of the rib to the second end of the rib, such that the first and second cantilevered portions together form a generally circular shape. Embodiments of locking mechanisms may include a button and orifice locking mechanism and/or a tab and channel locking mechanism. In a relaxed state in which the locking mechanism is not engaged, the rib preferably defines a non-circular, generally spiral shape.

The invention relates to a fluid-transfer coupling device designed to couple a rigid male endpiece (30) to a flexible female pipe (20) and to the production method therefor. The device comprises: a sleeve (10) for gripping around the pipe and locking the endpiece, the sleeve having a radially inner part (18) surrounding an annular sealing lining (50) mounted in abutment on the endpiece; and a metal socket (40) having a tubular portion (41) gripped by the pipe and ending in a collar formed by a radial step (43) which extends in an axial end (44) and has a radial height, the axial end being mounted inside and in contact with the radially inner part and forming the base of a groove receiving the lining, the device comprising means for fitting the sleeve to the collar and comprising a continuous peripheral projection (13) formed in one piece with the sleeve. According to the invention the projection projects radially in abutment against the step over most of the radial height.
