ABSTRACT:
A trap accessory, for selective coupling between a suction conduit and an aspirator includes: an elongated housing having a through passage; an elongated retainer slidably received in the housing passage, and having a through passage; and a filter element retained in the housing passage by said retainer. The housing is provided with a coupling nipple for coupling to a complementary coupling orifice in the suction conduit; and the retainer is provided with a coupling orifice for coupling to a complementary coupling nipple of the aspirator.
