An infusion set includes a base having a cannula for delivering a liquid medicament on a distal side for placing on a patient and a projection and recess and/or an annular groove on a proximal side. A connector for connection to an infusion device includes a protrusion on a distal side. The base and the connector are rotatably connectable to each other. The protrusion of the connector may be engaged with the projection and recess of the base such that, upon relative rotation between the connector and base, an acoustic and/or tactile signal indicates that the connector is connected incorrectly to the base; and/or the protrusion of the connector may be brought into engagement with the annular groove of the base such that the connector is rotatable relative to the base without causing noise and/or a tactile signal to indicate that the connector is connected correctly to the base.

The present invention provides a catheter head including a cannula housing, a needle holder connectable to the cannula housing and a guide sleeve associated with the needle holder for positioning and guiding a connecting needle, and for being narrowly slide-guided over a portion of said cannula housing.
