Abstract

The present invention relates to a downhole tool assembly comprising : - a tool body (1),(101) comprising at least one pocket (4),(104) for insertion of a cartridge (5), (105) and; - at least one cartridge (5), (105); said cartridge (5), (105) being fastened in the pocket (4), (104) in at least two different locations by respective fastening elements (8), (9); (108), (109) to be screwed into said pocket (4), (104), characterized in that said cartridge comprises abutment means (62), (72); (162), (172); (14), (15); (114), (115) for constraining the movement of each fastening element (8), (9), (108), (109) in its axial direction and away relative to the tool body (1) (101), and in that the dimensions of said cartridge relative to the dimensions of said pocket are selected such that there is a clearance fit between said cartridge and said pocket, such that said cartridge (5), (105) is insertable into the pocket or removable from said pocket following a single direction, and gets blocked into the pocket when the said cartridge is tilted to an angle exceeding a predetermined angle relative to said single direction. In other aspects, the present invention relates to a method for inserting said cartridge into said pocket and to a method for removing said cartridge from said pocket.
