Mating sphere to tube

The title is simple, but the problem is not. I have a very basic mating situation where i'm trying to mate 6 12mm OD hollow tubes to 6 sphere within my assembly. The two object are seen below:

So i want to mate them so that the inner edge of the tube is coincident to the surface of the sphere (To move freely around it) As shown below:

Now this is all well and good! but sometimes it mates to the other side of the sphere for some reason, as shown below:

Does anyone know how to make it only mate the the outside shell of the sphere? These piece are within a moving assembly and when they move, the mate can randomly swap from one side to the other which ruins the geometry of the assembly. This is what it's causing:

'Joint A' is one of the mates that has, in office terms 'gone to the dark side'. Because of this, 'Joint B' can no longer mate properly.

 

So to recap: Hollow tube mating to a sphere, but mating from one side to the other and creating invalid geometrys. I need some way of preventing it from mating to the inside of the sphere.

 

Thanks in Advance!!
