A hose coupling device (100) comprising:a main body (110) defining a through channel (112) for water flow between a first end (114) of the device (100) to a second end (116) of the device (100), the through channel (112) extending along an axis (118) of the device (100), the main body (110) further defining a coupler receiver portion (140) disposed at the first end (114) of the device (100) and a hose coupling portion (150) disposed at the second end (116) of the device (100); a sleeve portion (120) slidably engaging the main body (110) to releasably engage a coupler received in the coupler receiver portion (140) based on movement of the sleeve portion (120) in an axial direction (152); and a screw nut (130) disposed proximate to the hose coupling portion (150) to selectively facilitate engagement of the hose coupling portion (150) with a hose (170) inserted at the hose coupling portion (150) by exerting a clamping force on the hose (170) responsive to tightening of the screw nut (130), wherein the screw nut (130) comprises an annular body having first end (200) and a second end (210), wherein an internal periphery of the annular body includes a threaded portion (212) at the first end (200) of the annular body, wherein an external periphery of the annular body includes a haptic region (180) extending around the external periphery, the haptic region (180) being disposed at a portion of the external periphery that is spaced apart from both the first end (200) and the second end (210) of the annular body, the haptic region (180) extending over less than half of a length of the screw nut (130 in the axial direction (152). |
