1. An end cap for a carriage of a linear guide, the end cap comprising:
a closed lubrication port being openable by operatively connecting a lubrication fitting to said closed lubrication port, said lubrication port having a blind hole and a protrusion arranged on a bottom of said blind hole, said protrusion being configured for abutting against the lubrication fitting when the lubrication fitting is operatively connected to said lubrication port for opening said lubrication port, said lubrication port being openable by substantially fully inserting the lubrication fitting in said blind hole and exerting a force on said protrusion.
 
10. An end cap for a carriage of a linear guide, the end Cap comprising:
a closed lubrication port being openable by operatively connecting a lubrication fitting to said closed lubrication port, said lubrication port having a blind hole and a protrusion arranged on a bottom of said blind hole, said protrusion being configured for abutting against the lubrication fitting when the lubrication fitting is operatively connected to said lubrication port for opening said lubrication port, said protrusion defining a ramp having a contact section at an upper end for contacting said lubrication fitting upon operatively coupling said lubrication fitting to said lubrication port, said lubrication port being openable by inserting the lubrication fitting into said blind hole and exerting a force on said protrusion.
 
11. An end cap for a carriage of a linear guide, the end cap comprising:
a closed lubrication port being openable by operatively connecting a lubrication fitting to said closed lubrication port, said lubrication port having a blind hole and a protrusion arranged on a bottom of said blind hole, said protrusion being configured for abutting against the lubrication fitting when the lubrication fitting is operatively connected to said lubrication port for opening said lubrication port, said lubrication port containing an opening section configured for hinging upon operatively coupling said lubrication fitting to said lubrication port, said lubrication port being openable by inserting the lubrication fitting into said blind hole and exerting a force on said protrusion.
