Abstract: The present invention relates to a device forming an infrared decoy comprising a pyrotechnic priming part (150), a composition (121) suited to emitting radiation in the infrared domain, and a protective casing (130) for protecting the composition (121) and formed of a plastic sleeve, characterized in that at least one out of a body (150) of the initiation pyrotechnic part and/or of a plug (140) that blanks off the sleeve (130) has an annular groove (152, 142) that opens onto its external periphery and communicates with at least one longitudinal duct (154, 156; 144, 146) which opens onto an end of the body (150) or of the plug (140) in order to accept a polymerizable adhesive tape that bonds the body (150) and/or the plug (140) to the sleeve (130).
