A pipe connection assembly is provided including a first pipe having a first end and a second end; a second pipe including an insertion end extending in a lengthwise direction of the second pipe; and a fixing member. The second pipe includes a first protrusion protruding radially outward from the insertion end, and the insertion end is inserted into the second end of the first pipe such that the first protrusion presses radially outward on the first pipe thereby creating a second protrusion protruding radially outward from a pipe wall of the first pipe. The fixing member is sleeved around an outer periphery of the first pipe and is disposed in the lengthwise direction between the second protrusion and the second end of the first pipe.

A purpose is to render a gripping operation of grip tabs more stable. A hose clamp includes a clamp body formed by bending a plate spring into an annular shape while two ends of the plate spring are caused to cross each other on a circumferential plane and grip tabs formed to be raised radially outward from both ends of the clamp body, respectively. An expanded-diameter state of the clamp body is retained when a locking claw is locked by a catch. The clamp body is released from the expanded-diameter state when a gripping operation is further carried out in this state. The second grip tab has a distal end formed to be wider than a distal end of the first grip tab. The distal ends of the grip tabs are bent in respective directions in which the distal ends depart from each other with respect to a thicknesswise direction, thereby serving as bent portions for the gripping operation, respectively.

In a tool for mounting and dismounting a pipe clamp provided by the present creation, a first end portion and a movable second end portion are separately disposed on a base, and a connecting rod mechanism is used to convert circular motion into linear motion of the second end portion by force, so as to reduce the distance between the second end portion and the first end portion, thereby achieving an effect that the annular inner diameter of a pipe clamp is increased when the pipe clamp is held between the first end portion and the second end portion.

The invention relates to a connecting arrangement having a connecting piece (2) and a hose (3), wherein the hose (3) is pushed with one hose end (5) onto the connecting piece (2). In order to be able to ensure secure retention even during tool-free mounting, a press ring (4) is arranged at the hose end (5), surrounding the hose (3) on the outside, wherein the press ring (4) is retained on the hose end (5) by a friction fit. The invention further relates to a respective press ring.

According to one embodiment, a hose clamp has a leaf spring body, a slit and a first knob piece at one end, and an insertion piece and a second knob piece at the other end. An interlocking piece is formed in the first knob piece, and an engaging holding part is formed in the second knob piece. When the hose clamp is viewed from the outside in the radial direction while the leaf spring body is in a free state of being compressed, the first knob piece and the second knob piece are extended outward in the width direction so as to be separated.

A smart hose system includes a hose and a clamp monitor secured to the hose and in proximity to a portion of the hose at which a clamp is to be secured. The clamp monitor is configured to responsively interact with the clamp and includes a signal generator configured to provide a first response to an inquiry signal with the clamp being in a first state and provide a second response with the clamp being in a second state.

A reciprocating compressor is provided. The reciprocating compressor may include a discharge hose configured to discharge a refrigerant compressed in a cylinder, a connector coupled to the discharge hose and provided inside of the discharge pipe, and a hose fixing member provided on an outer circumferential surface of the discharge hose and configured to support the discharge hose, thereby stably coupling the discharge hose with the discharge pipe.
