In an embodiment of the invention, the inner diameter may be variable presenting a reduced diameter towards first connector end or towards second connector end. The diameter in accordance with this embodiment, is continuously reduced along the length of the connectors towards first connector end or towards second connector end. The diameter in accordance with this 18 embodiment, may be reduced along the length of the connectors towards first connector end or towards second connector end by up to about 30%. For example, up to about 25% or up to about 20%, up to about 15%, or up to about 10%. The inner diameter may thus present a conical shape with a cut-off end being first connector end or second connector end. In an exemplary embodiment, the inner diameter is reduced towards second end. In an exemplary embodiment, the inner diameter may be about 30 mm to about 90 mm. For example, about 40 mm to about 80 mm, about 40 mm to about 70 mm, about 40 mm to about 60 mm, or about 30 mm to about 60 mm. In one exemplary embodiment, the inner diameter may be about 48 mm, or about 50 mm, or about 55 mm.

In one or more embodiments, the outer diameter of first portion is substantially similar, or similar to the outer diameter of second portion. In one or more embodiments, the outer diameter of the herein disclosed connectors may be substantially constant along the entire length thereof. In an embodiment of the invention, the outer diameter may be variable presenting a reduced diameter towards first connector end or towards second connector end. The diameter in accordance with this embodiment, is continuously reduced along the length of the connectors towards first connector end or towards second connector end.

In an exemplary embodiment, the outer diameter may be about 30 mm to about 100 mm. For example, about 40 mm to about 90 mm, about 40 mm to about 80 mm, about 40 mm to about 70 mm, about 40 mm to about 60 mm, or about 30 mm to about 60 mm. In an exemplary embodiment, the outer diameter of the tube may be about 50 mm, or about 55 mm.

In an embodiment of the invention, first portion may have a length of about 30 mm to about 70 mm. For example, about 30 mm to about 60 mm, about 40 mm to about 55 mm, or about 45 mm to about 55 mm. In an embodiment of the invention, first portion has a length of about 50 mm. In an embodiment of the invention, first portion has a length of at least, or above about 30 mm. In an embodiment of the invention, first portion has a length of at least, or above about 35 mm, or at least, or above about 40, or at least, or above about 45 mm, or at least, or above about 50 mm. 19 In one or more embodiment, first portion of the herein disclosed connectors includes a first slope which declines towards first connector end. First slope allows the coupling of the first portion and engagement thereof with a first irrigation device.

In one or more embodiment, second portion of the herein disclosed connectors includes a second slope which declines towards second connector end. Second slope allows the coupling of the second portion and engagement thereof with a second irrigation device.

The enabled engagement or coupling is thus safe preventing possible damages for the inner portion of the irrigation device(s). In one or more embodiments, the safe engagement means that no damage is caused to the irrigation device with which the herein disclosed connector is engaged with. For example, in cases where the irrigation device(s) include(s) seals (such as an O-ring) at the internal surface thereof, the slope prevents possible damages, such as dislocations and ruptures to the seals.

In one or more embodiments, the declined first and/or second slopes define(s) an angle of less than about 85° between the slope and a horizontal axis of the connector. For example, the angle is less than about 80°. For example, the angle is between about 20° and about 80°, between about 30° and about 70°, between about 30° and about 50°, or between about 40° and about 60°.

In one or more embodiments, the slope has a length of about 3 mm to about 10. For example, about 4 mm to about 8 mm, or about 5 mm to about 7 mm.

In one or more embodiments, the herein disclosed connectors include an intermediate portion positioned between first portion and second portion. In one or more embodiments, the intermediate portion that includes a stop member. In one or more embodiment, the stop member is configured to allow for a secure engagement with the first irrigation device via gripping arms. In one or more embodiments, the stop member is configured to restrict the engagement with the first irrigation device to the first portion.

The herein disclosed connectors thus allow an engagement between pipelines, pipeline tools, or pipes or portions thereof by insertion of the first and/or second portion(s) of the connectors to the pipelines, pipeline tools, or pipes and/or portions thereof. The obtained engagement between the herein disclosed connectors and pipelines/pipeline tools/pipes and/or portions thereof may be secured by securing members, such as gripping arms and/or a nut.

The connector 10 includes a hollowed longitudinal tube 12 extending between a first connector end 14 and a second connector end 16. First connector end 14 is open allowing passage therethrough of irrigation water or any other type of liquid. Second connector end 16 is closed allowing the connector to be used as an irrigation end of line or line-end, or pipe end.

Connector 10 is thus usable for capping or ending or terminating an irrigation line.

Connector 10 includes a first portion 18, a second portion 20 and an intermediate portion 21. First portion 18 extending between first connector end 14 and intermediate portion 21 and configured for an engagement with a tubular portion of an irrigation device in a sealed manner, and a second portion 20 extending between second connector end 16 and intermediate portion 21 and configured to allow end of flow of the irrigation line. Second portion 20 is further optionally configured to allow drainage of irrigation water and/or drainage of waste of irrigation water. Such an arrangement and configuration of the connector 10 allows an improved flow of the irrigation system and prevention of blockages within the irrigation pipes. Further, the particular configuration of the connector provides stability of the entire pipe system.

Slope 24 allows the insertion of the first portion 18 and engagement thereof with a first irrigation device. The insertion via slope 24 is smooth and prevents possible damages for the inner portion of first irrigation device. For example, in cases where first irrigation device includes seals/gaskets (such as an O-ring) at the internal surface thereof, the slope 24 prevents damages, such as dislocations and ruptures to the seals/gaskets.

Slope 24 defines an angle α of up to about 85° between slope 24 and a horizontal axis X of connector 10 (shown in FIG. 5). In one or more embodiments, slope 24 defines an angle α of up to about 70° between slope 24 and a horizontal axis X of connector 10.
