A catheter insertion needle assembly (100) including a generally elongated body (110), a slider assembly (120), and a needle housing (126) with a needle (130). The elongated body has a proximal end (114) and a distal end (112), a needle guard (140) disposed at the distal end of the body in a needle guard plane, a first or distal locking member (150), and a second or proximal locking member (118). The slider assembly (120) includes a slider (122) that is slidably disposed on the body (110) Needle (130) has a distal tip (134) and a cannulating portion (132) extending therethrough. A first locking tab (121) is releasably engageable with the first locking member (150) and a second locking portion is lockably engageable with the second locking member (118). The first locking tab (121) is releasable from the first locking member to allow the slider (122) to slide between a distal position relative to the body (110) wherein the tip (134) extends distally of the needle guard (140), and a proximal position relative to the body wherein the tip (134) is disposed within the needle guard plane. When the slider (122) is disposed at the proximal position, the second locking portion engages the second locking member (118) to preclude the slider (122) from sliding distally relative to the body (110).
