The Hosel (one 's') is the socket or neck in the head of a golf club into which the shaft is inserted.
The socket is known as the hosel, it is where the head is connected to the shaft.

Use an abrasive on shaft and inside hosel, clean with acetone or alcohol, let dry, use 2 part epoxy on shaft and in hosel, join the 2 together, wipe off excess glue, allow to cure 24 hours before using.
Assuming the broken club is a driver, the area on the shaft just above the hosel impacts at a teed up ball rather than the club face. The stationary weight of a golf ball is sufficient to strain the tensile strength of a graphite shaft. With a club head attached at the very end of the club, it further increases the momentum of a downswing. This is mostly caused by addressing the ball too close to the body and an incorrect swing plane going back. For an iron, a breakage could be mainly caused by hitting the toe of the club into a relatively hard surface in the down swing. This usually happens to a graphite shafted game improvement iron. The reason being that game improvement irons have larger and wider club face area, in which when it is swung at a particular speed with only its toe part hitting the surface, the tensile strength of the shaft at the hosel is at its most vulnerable. This is mostly caused by the use of a non-custom fitted iron where certain compensations (maybe due to shaft length and body height not ideal) in a swing occur. Also may be caused by incorrect swing plane.
Offset irons are easier to hit because of the position of the club at impact. At impact, the hands should be leading the ball, therefore having the club face lag behind. The offset of clubs allow non-pros to have a similar club location at impact, and this will give you a better ball flight.
Purely cosmetic. When the part where the shaft meeting the hosel is exposed it can look rather ugly, and it can also catch on things when being put into your bag again.
