Abstract
The present invention is a device where a needle cap rim is captured between a front wall and abutment means behind it. This is done by making aligned slots in the front wall and abutment means with side to side widths greater than the diameter of the needle cap body (without ridges) but less than the outside diameter of the needle cap rim. However, the rim of the needle hub is located outside the front wall slot, where the intervening needle hub rim to needle shaft part of the needle hub passes through the front wall slot and into the needle cap for friction fit contact.
