Reel assembly for a housing

A reel assembly for a watering hose for coupling within a housing, comprising:

• an axle;
• a reel defining a rotational axis, wherein the reel is rotatably mounted around the axle to allow winding of the watering hose on the reel;
• a frame which houses the reel;
• and
• one or more fixing units to removably fix the reel assembly inside the housing;
• wherein the housing includes a pair of side walls and a pair of front walls,
• wherein at least one of the pair of side walls and the pair of front walls includes a housing inlet, wherein the housing inlet is or can be associated with a water connector to fluidly couple the watering hose with a fluid line or hose to supply water from an external fluid source;
• wherein the reel assembly further comprises a blocking mechanism that operatively couples with the reel assembly and cooperates with the reel for selective rotation of the reel;
• and
• wherein the blocking mechanism disallows rotation of the reel in absence of coupling of the reel assembly within the housing,
• wherein the blocking mechanism is a turning block in form of a movable screw or a bolt that is fixed to the frame, wherein the turning block is one or more of substantially parallel, perpendicular or pivoted with respect to the rotational axis of the reel.
