The present invention relates to the field of enclosures for electronic circuits and in particular to applications, for example payment card systems, where it is necessary to provide some physical security to prevent unauthorised access to a circuit and more particularly to the data contained within memory devices in the circuit. The present invention provides an improved housing overcoming problems associated with prior art housing and in particular provides a housing that allows for replacement and/or repair of an underlying circuit at a relatively low cost. This is achieved by provision of a single piece construction security housing having conductive patterns integrally provided thereon. In particular, a first embodiment of the invention provides a security housing for mounting in use on a circuit board to protect an associated circuit, comprising: a plurality of electrical contacts for making electrical contact with the circuit board, a cover, a plurality of side walls, where the plurality of side walls and cover define a space for accommodating the associated circuit, and at least one pattern of conductive tracks electrically connected to the electrical contacts and integrally formed with the plurality of side walls and the cover in a single piece construction. <IMAGE>
