A needle protection apparatus, comprising:

• a collar having first locking portions;
• a housing pivotable relative to said collar, said housing having two side walls each having a second locking portion that coactingly mates with a corresponding one of said first locking portions when said housing is pivoted to a position along a longitudinal axis of said collar;
• a barrier extending from said collar to prevent the respective edges of said side walls of said housing where said second locking portions are located from being exposed once said housing is pivoted to said position along said longitudinal axis.

Safety device, comprising:

• a collar having a longitudinal axis and two ears extending from opposite sides of said collar orthogonal to said longitudinal axis;
• a housing having two side walls for defining a longitudinal slot therebetween pivotably connected to said collar, each of said two side walls having a groove or finger that coactingly mates with a corresponding one of said ears when said housing is pivoted to a position in alignment with said longitudinal axis;
• two arms each extending from said collar proximately to a corresponding one of said ears to prevent respective sections of edges of said side walls of said housing from being exposed once said housing is pivoted to said alignment position.
