Abstract: A detachable connection between two housing sections (1, 2) has two cooperating latching elements formed by a resilient tongue (7) with a peripheral portion (9) on one housing section (1) and a projection (10) on the other housing section (2), the projection (10) engaging behind the peripheral portion (9) in an interconnected condition of the housing sections. In order to enable the housing sections to be separated easily from one another, the housing sections have two other cooperating latching element formed by a second projection (15) and a second peripheral portion (14), one of the latching elements being connected to the tongue (7). To unlatch the housing sections, the resilient tongue (7) is pressed back, thereby unlatching the first projection (10) and also locking the tongue against springing back in that the second projection (15) engages behind the second peripheral portion (14).

Abstract: A multiusage thermometer comprises a body portion capable of selectively detachably engaging thereto at least a first sensing portion, a second sensing portion, a third sensing portion and a fourth sensing portion each of said sensing portions having a first engaging member at a first end thereof, said body portion integrally forming a second engaging member at one end thereof for electrically and complementarily connecting thereto said first engaging member of each of said sensing portions. This invention offers a thermometer being multiusable and having a body portion capable of being selectively detachably engaged with other sensing portions of various usages based on the situation one faces.
